##2.2 Definitions
###2.2.1 Clock
Definition: A Clock references to a time capable hardware part of a microcontroller.
11 of 186 Document ID 421: AUTOSAR_SWS_SynchronizedTimeBaseManager
- AUTOSAR confidential -
Specification of Synchronized Time-Base Manager AUTOSAR CP R19-11
###2.2.2 Global Time Master
Definition: A Global Time Master is the global owner and origin for a certain Time
Base and on the top of the Time Base hierarchy for that Time Base.
###2.2.3 Synchronized Time Base
Definition: A Synchronized Time Base is a Time Base existing at a processing entity (actor / processor / node of a distributed system) that is synchronized with Time Bases at different processing entities. A Synchronized Time Base can be achieved by time protocols or time agreement protocols that derive the Synchronized Time Base in a defined way from one or more physical Time Bases. Examples are the network time protocol (NTP) and FlexRay time agreement protocol.
###2.2.4 Time Base
Definition: A Time Base is a unique time entity characterized by:
Progression of time, which denotes how time progresses, i.e. the rate (i.e. the rate is derived from a local quartz oscillator) and absolute changes of the time
value at certain point in times (e.g. effects of offset correction in FlexRay).
Ownership, which denotes who is the owner of the time base. A distributed FlexRay Time Base e.g. has multiple owners and the progression of time with respect to rate and offset corrections is a result of involving a subset of FlexRay
nodes.
Reference to the physical world, i.e. whether the Time Base is a relative Time
Base counting local operation time of an ECU or representing an absolute time
like UTC. A Time Base can have more than one reference, e.g. it can be a relative time which in combination with an offset value also represents an absolute time.
###2.2.5 Time Base Provider
Definition: A Time Base Provider is the role that a TSyn module takes for a given Time Base. Therefore a TSyn module can contain only one Time Base provider or more than one Time Base provider. Time Base providers are either of type importer or exporter, whereas an importer acts as Time Slave and an exporter acts as Time Master. A Time Gateway consists of one Time Base importer and one or more Time Base exporters for a given Time Base. In order to limit the terminology importers are denoted as slaves and exporters are denoted as masters.
###2.2.6 Time Communication Port
Definition: A Time Communication Port is a physical communication interface (in AUTOSAR coverable by the item: Physical Connector) at an ECU which is used to transport time information.
###2.2.7 Time Communication Service
Definition: A Time Communication Service is an interaction between Time Bases which is performed by Time Base providers. Time communication services are message based between a Time Master and one or more Time Slaves or between one Time Slave and his Time Master.
###2.2.8 Time Base Customer
a) Active Customer
This kind of customer autonomously calls the Synchronized Time-Base Manager either
To read time information (arrow “2” in Figure 1) from the Synchronized Time-Base Manager or
To update (arrow “3” in Figure 1) the Time Base maintained by the Synchronized Time-Base Manager according to application information.
b) Triggered Customer
This kind of customer is triggered by the Synchronized Time-Base Manager (arrow “1” in Figure 1). Thus, the Synchronized Time-Base Manager itself is aware of the required functionality of the customer, and uses the defined interface of the customer to access it.
This functionality is currently limited to synchronization of OS ScheduleTables.
c) Notification Customer
This kind of customer is notified by the Synchronized Time-Base Manager (arrow “4” in Figure 1), if the following Time Base related events occur:
14 of 186
Time Base status has changed (e.g. a timeout has occurred for a Time Base)
Time Base value has reached a given value, which has been previously
set by the customer (arrow “5” in Figure 1).
###2.2.9 Time Domain
Specification of Synchronized Time-Base Manager AUTOSAR CP R19-11
Definition: A Time Domain denotes which components (e.g. nodes, communication systems) are linked to a certain Time Base. A Time Domain can contain no or more than one Time Sub-domains. If the timing hierarchy of a Time Domain contains no Time Gateways, i.e. all nodes are connected to the same bus system, then there is no dedicated Time Sub-domain which otherwise would be equal to the Time Domain itself.
###2.2.10 Time Gateway
Definition: A Time Gateway is a set of entities where one entity is acting as Time Slave for a certain Time Base. The other (one or more) entities are acting as Time Masters which are distributing this Time Base to sets of Time Slaves. A Timesync ECU can contain multiple Time Gateways. A Time Gateway can be connected to different types of bus systems (e.g. the slave side could be connected to a FlexRay bus whereas the master side could be connected to a CAN bus system).
###2.2.11 Time Hierarchy
Definition: The Time Hierarchy describes how a certain Time Base is distributed, starting at the Global Time Master and being distributed across various Time Gateways (if present) to various Time Slaves.
###2.2.12 Time Master
Definition: A Time Master is an entity which is the master for a certain Time Base and which propagates this Time Base to a set of Time Slaves within a certain segment of a communication network, being a source for this Time Base.
If a Time Master is also the owner of the Time Base then he is the Global Time Master. A Time Gateway typically consists of one Time Slave and one or more Time Masters. When mapping time entities to real ECUs it has to be noted, that an ECU could be Time Master (or even Global Time Master) for one Time Base and Time Slave for another Time Base.
Special Case “Pure Local Time Master“:
A Pure Local Time Master is an entity which is the master of a Pure Local Time Base and which does therefore not propagate this time base to any Time Slave.
###2.2.13 Time Slave
Definition: A Time Slave is an entity which is the recipient for a certain Time Base within a certain segment of a communication network, being a consumer for this Time Base.
###2.2.14 Time Sub-domain
Definition: A Time Sub-domain denotes which components (e.g. nodes) are linked
to a certain Time Base whereas the scope is limited to one communication bus.
###2.2.15 Timesync ECU
Definition: A Timesync ECU is an ECU which is part of a Time Domain by
containing one or more Time Slaves or Time Masters.
###2.2.16 Timesync Module
Definition: Timesync Modules (TSyn modules) are bus specific modules to receive or transmit time information on bus systems by applying bus specific mechanisms. A Timesync module can serve multiple communication buses of the same type.
###2.2.17 Virtual Local Time
Definition: The Virtual Local Time is a time which is driven by the OS counter or a hardware clock and which in turn drives a Synchronized Time Base. The associated Synchronized Time Base has an offset to the Virtual Local Time. For Time Slaves there is usually also a deviation in rate caused by different clock drifts of the HW reference clocks used by Time Master and Time Slave.
The term Virtual Local Time describes a Time Base whose time progresses monotonously without jumps.
Virtual Local Time Bases are necessary for interpolating
local instances of Synchronized Time Bases (in either Master or Slave)
Pure Local Time Bases
and Offset Time Bases (in case of rate correction)
In addition, Virtual Local Time Bases can be used to measure timespans, i.e., for rate correction measurement intervals or timeouts.
Virtual Local Time Bases are based on a hardware clock and can be derived from various sources:
OS counter
GPT counter
Ethernet freerunning counter (used for ingress and egress timestamping)
It is possible to use different Virtual Local Time Bases in parallel.
Although the different counter sources vary regarding tick duration and counter width, each derived Virtual Local Time Base has the same width (64 bit) and tick duration (1 ns).
To achieve this, it is necessary to count overflows of the counters and to convert counter specific tick durations if required.
###2.2.18 Time Correction
Definition: Time Correction in Time Slaves is the process of adjusting the value of the local instance of the Time Base to the value of the Global Time Base.
In Time Masters, Time Correction is the process of eliminating the deviation of an Offset Clock compared to its corresponding Synchronized Time Base.
Time Correction can be divided into Rate Correction, which corrects rate deviations and Offset Correction, which corrects absolute time deviations. Offset Correction can be furthermore divided into (Offset Correction By) Jump Correction or (Offset Correction By) Rate Adaption.
2.2.18a Rate Correction
Definition: Rate Correction corrects the rate-deviation of a local hardware reference clock. This correction is done by a multiplicative correction factor which is used in addition to the clock‘s preconfigured rate. Rate Correction determines the correction factor in the scope of a measurement. This correction factor is however not fixed but updated after each successful measurement.
###2.2.19 Offset Correction
Specification of Synchronized Time-Base Manager AUTOSAR CP R19-11
Definition: Offset Correction corrects absolute time deviations (offsets). Depending on the magnitude of the offset and the configuration of StbM, this correction is either performed by Jump Correction or Rate Adaption.
Offset Correction is independent from Rate Correction. It is performed each time the local instance of the Time Base is synchronized to its Global Time Base.
###2.2.20 Jump Correction
Definition: Jump Correction corrects absolute time offsets in a single step by adding the offset to the local instance of the Time Base (which is equivalent to taking over the value of the Global Time Base).
###2.2.21 Rate Adaption
Definition: Rate Adaption corrects time offsets gradually within a predefined timespan. Hereto, Rate Adaption switches the rate of the local instance of the Time Base temporarily to a different value. This rate is chosen to completely eliminate the offset within the preconfigured timespan.

183 Specification of a Transport Layer for SAE J1939
2 Glossary, Acronyms, and Abbreviations
The following table presents a glossary of J1939 specific terms. For all other terms, please check the AUTOSAR Glossary.
Glossary Term | Explanation |
---|---|
Address Claiming | Address Claiming forms the network management of SAE J1939 defined in the standard document SAE J1939/81. Address claiming assigns a temporary 8-bit identifier to each ECU connected to one J1939 network. Within this network, the 8-bit identifier is unique. The 8- bit identifier is used as source and target address of parameter groups (messages) transferred via the J1939 network. The address claiming procedure is based on the exchange of AddressClaimed messages (PGN 00EE00). |
J1939 Diagnostics | The SAE J1939 diagnostic layer is defined in the standard document SAE J1939/73. The J1939 diagnostics is functionally similar to the UDS diagnostics, and has recently been extended to support OBD for emission relevant values. |
Parameter | A parameter is a signal of the SAE J1939 application layer. Parameters are uniquely identified by the SPN. |
Parameter Group | A parameter group is a message of the SAE J1939 application layer. Each parameter group contains several parameters (signals), and is uniquely identified by the PGN. |
Transport Protocol | The SAE J1939 transport protocol is used for the segmented transmission of messages with more than 8 bytes of data. The transport protocol is defined in the network layer standard document (SAE J1939/21). |

###1.4 Technical Terms
All technical terms used throughout this document – except the ones listed here – can be found in the official AUTOSAR glossary [11] or the Software Component Template Specification [2].
Term | Description |
---|---|
application mode manager | An application mode manager is an AUTOSAR software- component that provides the service of switching modes. The modes of an application mode manager do not have to be standardized. |
associated RTE Implementation Plug-In | The RTE Implementation Plug-In which is assigned to a communication graph, ExclusiveArea, mode machine instanceordistributed shared mode groupandthere- fore handles all accesses via RTE APIs, SchM APIs or RTE in- ternal code. |
AutosarDataPrototype implementation | Definitions and declarations for non automatic1 memory objects which are allocated by the RTE and implementing AutosarDat- aPrototypes or their belonging status handling. |
BswSchedulableEntity activation | The activation of a BswSchedulableEntity is defined as the activation of the task/ISR2 that contains the BswSchedula- bleEntity and eventually includes setting a flag that tells the glue code in the task/ISR2 which BswSchedulableEntity is to be executed. |
BswSchedulableEntity start | A BswSchedulableEntity is started by the calling the C- function that implements the BswSchedulableEntity from within a started task/ISR2. |
’C’ typed PerInstanceMemory | ’C’ typed PerInstanceMemory is defined with the class PerIn- stanceMemory. The type of the memory is defined with a ’C’ typedef in the attribute typeDefinition. |
client | A client is defined as one ClientServerOperation in one RPortPrototype of one Software Component instance. For the definition of the client neither the number of ServerCallPoints nor RunnableEntity accesses to the ServerCallPoint are relevant. A Software Component instance can appear as sev- eral clients to the same server if it defines ServerCallPoints for several PortPrototypes of the same PortInterface’s ClientServerOperation. |
CodeGenerationTime variability | Variability defined with an VariationPoint or Attribute- ValueVariationPoint with latest bindingTime CodeGenera- tionTime. |
coherency group | A set of implicit read accesses and implicit write accesses for which the RTE cares for data coherency. Please note that in the context of this specification the definition of co- herency includes that • readdatavaluesofdifferentVariableDataPrototypes have to be from the same age, except the values are changed by implicit write accesses belonging to the coherency group • written data values of different VariableDataProto- types are communicated to readers NOT belonging to the coherency group after the last implicit write access belonging to the coherency group. |
coherent implicit data access | An implicit read access or an implicit write ac- cess which belongs to coherency group. Therefore it is referenced by a RteVariableReadAccessRef or RteVari- ableWriteAccessRef belonging to a RteImplicitCommu- nication container which RteCoherentAccess parameter is set to true. |
coherent implicit read access | An implicit read access which belongs to coherency group. Therefore it is referenced by a RteVariableReadAc- cessRef belonging to a RteImplicitCommunication con- tainer which RteCoherentAccess parameter is set to true. |
coherent implicit write access | An implicit write access which belongs to coherency group. Therefore it is referenced by a RteVariableReadAc- cessRef or RteVariableWriteAccessRef belonging to a RteImplicitCommunication container which RteCo- herentAccess parameter is set to true. |
common mode machine in- stance | A ‘common mode machine instance’ is a special ‘mode machine instance’ shared by BSW Modules and SW-Cs: |
The RTE Generator creates only one mode machine in- stance if a ModeDeclarationGroupPrototype instantiated in a port of a software-component is synchronized (synchronized- ModeGroup of a SwcBswMapping) with a providedModeGroup ModeDeclarationGroupPrototype of a Basic Software Module in- stance. The related mode machine instance is called com- mon mode machine instance. | |
Communication Graph | The sum of all AbstractAccessPoints to elements of Port- Interfaces instantiated in PortPrototypes which are con- nected to each other, or the sum of all accesses from BswMod- uleEntitys to interface elements in a BswModuleDescrip- tions connected to each other. |
Data Communication Graph | The sum of all VariableAccesses to DataPrototypes in- stantiated in PortPrototypes which are connected to each other, or the sum of all VariableAccesses to DataProto- types in the InternalBehavior, or the sum of all BswVari- ableAccesses to DataPrototypes in BswModuleDescrip- tions connected to each other. |
Client Server Communication Graph | The sum of all ServerCallPoints to operations instantiated in PortPrototypes which are connected to each other inclu- sive the belonging server runnable. |
Trigger Communication Graph | The sum of all ExternalTriggeringPoints for triggers instantiated in PortPrototypes which are connected to each other inclusive the belonging triggered runnable. |
copy semantic | Copy semantic means, that the accessing entities are able to read or write the "copied" data from their execution context in a non concurrent and non preempting manner. If all accessing en- tities are in the same preemption area this might not require a real physical data copy. |
core local mode user group | In the case that mode users belong to different partitions which in turn are scheduled on different micro controller cores the over- all mode machine instance needs to be distributed cross core. Thereby some restrictions are only applicable between the mode users executed on the same micro controller core. |
All mode users of the same mode manager which belong to EcucPartition which in turn belong to OsApplications re- ferring to the same EcucCoreDefinition are belonging to the same core local mode user group. | |
data semantic | When data is distributed, the last received value is of interest (last-is-best semantics). Therefore the software implementation policy, stated in the swImplPolicy attribute of the SwDataDef- Props, shouldn’t be ’queued’. |
event semantic | When events are distributed the whole history of received events is of interest, hence they must be queued on receiver side. There- fore the software implementation policy, stated in the swIm- plPolicy attribute of the SwDataDefProps, will have the value ’queued’(corresponding to event distribution with a queue). |
execution-instance | An execution-instance of an ExecutableEntity is one in- stance or call context of an ExecutableEntity with respect to concurrent execution, see section 4.2.3. |
implicit read access | VariableAccess aggregated in the role dataReadAccess to a VariableDataPrototype |
implicit write access | VariableAccess aggregated in the role dataWriteAccess to a VariableDataPrototype |
incoherent implicit data access | An implicit read access or an implicit write ac- cesswhichdoesnotbelongtoacoherency group.Therefore it is NOT referenced by any RteVariableReadAccessRef or RteVariableWriteAccessRef belonging to a RteImplic- itCommunication container which RteCoherentAccess pa- rameter is set to true. |
incoherent implicit read access | An implicit read access which does not belong to a co- herency group. Therefore it is NOT referenced by any Rte- VariableReadAccessRef belonging to a RteImplicitCom- munication container which RteCoherentAccess parameter is set to true. |
incoherent implicit write access | An implicit write access which does not belong to a coherency group. Therefore it is NOT referenced by any RteVariableWriteAccessRef belonging to a RteImplic- itCommunication container which RteCoherentAccess pa- rameter is set to true. |
inter-ECU communication | The communication between ECUs, typically using COM is called inter-ECU communication in this document. |
intra-partition communication | The communication within one ECU is called intra-ECU com- munication in this document. It is a super set of inter-parti- tion communication and intra-partition communication. |
intra-ECU communication | The communication within one partition of one ECU is called intra-partition communication. In this case, RTE can make use of internal buffers and queues for communication. |
inter-partition communication | The communication within one ECU but between different par- titions, represented by different OS applications, is called in- ter-partition communication in this document. It may in- volve the use of OS mechanisms like IOC or trusted function calls. The partitions can be located on different cores or use different memory sections of the ECU. |
invalidateable | Invalidateable VariableDataPrototypes are Variable- DataPrototypes that have an invalidValue. |
LinkTime variability | Variability defined with an VariationPoint or AttributeValue- VariationPoint with latest bindingTime LinkTime. |
mode disabling | When a ‘mode disabling’ is active, RTE and Basic Software Schedulerdisablestheactivationofmode disabling depen- dent ExecutableEntitys. The ‘mode disabling’ is active during the mode that is referenced in the mode disabling depen- dency and during the transitions that enter and leave this mode. See also section 4.4.1. |
mode disabling dependency | A RTEEvent (respectively a BswEvent) that starts a RunnableEntity (respectively a BswSchedulableEntity) can contain a disabledMode (respectively disabledInMode) as- sociation which references a ModeDeclaration. This association is called mode disabling dependency in this document. |
mode disabling dependent ExecutableEntity | A mode disabling dependent RunnableEntity or a BswSchedulableEntity is triggered by an RTEEvent re- spectivelyaBswEventwithamode disabling dependency. RTE and Basic Software Scheduler prevent the activation of those RunnableEntity or BswSchedulableEntity by the RTEEvent / BswEvent, when the corresponding mode dis- abling is active. See also section 4.4.1. |
mode machine instance | The instances of mode machines or ModeDeclarationGroups are defined by the ModeDeclarationGroupPrototypes of the mode managers. |
Since a mode switch is not executed instantaneously, The RTE or Basic Software Scheduler has to maintain it’s own states. For each mode manager’s ModeDeclarationGroupPrototype, RTE or Basic Software Scheduler has one state machine. This state machine is called mode machine instance. For all mode users ofthesamemode manager’sModeDeclarationGroupPrototype, RTE and Basic Software Scheduler uses the same mode ma- chine instance. See also section 4.4.2. | |
mode manager | Entering and leaving modes is initiated by a mode manager. A mode manager is either a software component that provides a p-port typed by a ModeSwitchInterface or a BSW module which defines in its BswModuleDescription a ModeDeclara- tionGroupPrototype in the role providedModeGroup. See also section 4.4.2. |
ModeSwitchAck ExecutableEntity | A RunnableEntity or a BswSchedulableEntity that is trig- gered by a ModeSwitchedAckEvent respectively a BswMod- eSwitchedAckEventconnectedtothemode manager’sMod- eDeclarationGroupPrototype. It is called ModeSwitchAck ExecutableEntity. See also section 4.4.1. |
mode switch notification | The communication of a mode switch from the mode manager to the mode user using either the ModeSwitchInterface or providedModeGroup and requiredModeGroup ModeDeclara- tionGroupPrototypes is called mode switch notification. |
mode switch port | The port for receiving (or sending) a mode switch notification. For this purpose, a mode switch port is typed by a ModeSwitchIn- terface. |
mode user | An AUTOSAR SW-C or AUTOSAR Basic Software Module that depends on modes is called a mode user. The depen- dency can occur through a SwcModeSwitchEvent/BswMod- eSwitchEvent, a ModeAccessPoint for a provided/required mode switch port, or a accessedModeGroup for a providedModeGroup/requiredModeGroup ModeDeclara- tionGroupPrototype. See also section 4.4.1. |
NvBlockSwComponent | NvBlockSwComponent is a SwComponentPrototype typed an NvBlockSwComponentType. |
on-entry ExecutableEntity | A RunnableEntity or a BswSchedulableEntity that is trig- gered by a SwcModeSwitchEvent respectively a BswMod- eSwitchEvent with ModeActivationKind ‘entry’ is triggered on entering the mode. It is called on-entry ExecutableEntity. See also section 4.4.1. |
on-exit ExecutableEntity | A RunnableEntity or a BswSchedulableEntity that is trig- gered by a SwcModeSwitchEvent respectively a BswMod- eSwitchEvent with ModeActivationKind ‘exit’ is triggered on exiting the mode. It is called on-exit ExecutableEntity. See also section 4.4.1. |
on-transition ExecutableEntity | A RunnableEntity or a BswSchedulableEntity that is trig- gered by a SwcModeSwitchEvent respectively a BswMod- eSwitchEvent with ModeActivationKind ‘transition’ is triggered on a transition between the two specified modes. It is called on- transition ExecutableEntity. See also section 4.4.1. |

runnable activation | The activation of a runnable is linked to the RTEEvent that leads to the execution of the runnable. It is defined as the incident that is referred to by the RTEEvent. E.g., for a timing event, the corresponding runnable is activated, when the timer expires, and for a data received event, the runnable is activated when the data is received by the RTE. |
runnable start | A runnable is started by the calling the C-function that imple- ments the runnable from within a started task/ISR2. |

This saves memory and time. |
multicast operation | Simultaneous transmission of PDUs to a group of receivers, i.e. 1:n routing. |
data provision | Provision of data to interface modules.(a) direct data provision: data to be transmitted are provided directly at the transmit request. The destination communication interface may behave in two ways, either copy the data directly or defer the copy to a trigger transmit.(b) trigger transmit data provision: data to be transmitted are not provided at the transmit request, but will be retrieved by the interface module via a callback function |

2.1 GlossaryofTerms
Term | Definition |
---|---|
Access Right | An indication that an object (e.g. Task, ISR, hook function) of an OS-Application has the permission of access or manipulation with respect to memory, OS services or (set of) OS objects. |
Cardinality | The number of items in a set. |
Counter | An operating system object that registers a count in ticks. There are two types of counters: |
Hardware Counter | A counter that is advanced by hardware (e.g. timer). The count value is maintained by the peripheral “in hardware”. |
Software Counter | A counter which is incremented by making the IncrementCounter() API call (see SWS_Os_00399). The count value is maintained by the operating system “in software”. |
Deadline | The time at which a Task/Category 2 ISR must reach a certain point during its execution defined by system design relative to the stimulus that triggered activation. See Figure 2.1 |
Delay | The number of ticks between two adjacent expiry points on a schedule table.A pair of expiry points X and Y are said to be adjacent when: There is no expiry point Z such that X.Offset < Z.Offset < Y.Offset. In this case the Delay = Y.Offset-X.Offset. X and Y are the Final Expiry Point and the Initial Expiry Point respectively. In this case Delay = (Duration-X.Offset)+Y.Offset. When used in the text, Delay is a relative number of ticks measured from a specified expiry point. For example: X.Delay is the delay from X to the next expiry point. |
Deviation | The minimum number of ticks between the current position on an explicitly synchronized schedule table and the value of the synchronization count modulo the duration of the schedule table. |
Duration | The number of ticks from a notional zero at which a schedule table wraps. |
Execution Time | TASK, ISRs. Execution time includes the time spent in the error, pretask and posttask hooks and the time spent making OS service calls. |
Tasks(Execution Time) | The net time a task spends in the RUNNING state without entering the SUSPENDED or WAITING state excluding all preemptions due to ISRs which preempt the task. An extended task executing the WaitEvent() API call to wait on an event which is already set notionally enters the WAITING state. For multiple activated basic tasks the net time is per activation of a task. |
ISRs(Execution Time) | The net time from the first to the last instruction of the user provided Category 2 interrupt handler excluding all preemptions due to higher priority ISRs executing in preference. |
Execution Budget | Maximum permitted execution time for a Task/ISR. |
Expiry Point | The offset on a Schedule Table, measured from zero, at which the OS activates tasks and/or sets events. |
Initial Expiry Point | The expiry point with the smallest offset |
Final Expiry Point | The expiry point with the largest offset |
Hook Function | A Hook function is implemented by the user and invoked by the operating system in the case of certain incidents. In order to react to these on system or application level, there are two kinds of hook functions |
Application-specific | Hook functions within the scope of an individual OS- Application. |
System-specific | Hook functions within the scope of the complete system (in general provided by the integrator). |
Initial Offset | The smallest expiry point offset on a schedule table. This can be zero. |
Interarrival Time | See Figure 2.1. |
Basic Tasks(Interarrival Time) | The time between successively entering the READY state from the SUSPENDED state. Activation of a task always represents a new arrival. This applies in the case of multiple activations, even if an existing instance of the task is in the RUNNING or READY state. |
Extended Tasks(Interarrival Time) | The time between successively entering the READY state from the SUSPENDED or WAITING states. Setting an event for a task in the WAITING state represents a new arrival if the task is waiting on the event. Waiting for an event in the RUNNING state which is already set represents a new arrival. |
ISRs(Interarrival Time) | The time between successive occurrences of an interrupt. |
Interrupt Lock Time | The time for which a Task/ISR executes with Category 1 interrupts disabled/suspended and/or Category 2 interrupts disabled/suspended . |
Interrupt Source Enable | The switch which enables a specific interrupt source in the hardware. |
Interrupt Vector Table | Conceptually, the interrupt vector table contains the mapping from hardware interrupt requests to (software) interrupt service routines. The real content of the Interrupt Vector Table is very hardware specific, e.g. it can contain the start addresses of the interrupt service routines. |
Final Delay | The difference between the Final Expiry Point offset and the duration on a schedule table in ticks. This value defines the delay from the Final Expiry Point to the logical end of the schedule table for single-shot and “nexted” schedule tables. |
Forced OS- Application Termination | The operating system frees all system objects, e.g. forcibly terminates Tasks, disables interrupts, etc., which are associated to the OS-Application. OS- Application and internal variables are potentially left in an undefined state. |
Forced Termination | The OS terminates the Task/Category 2 ISR and does ”unlock” it’s held resources. For details see SWS_Os_00108 and SWS_Os_00109. |
Linker File | File containing linking settings for the linker. The syntax of the linker file depends on the specific linker and, consequently, definitions are stored “linker-specific” in the linker file. |
Lock Budget | Maximum permitted Interrupt Lock Time or Resource Lock Time. |
Master core | A master core is a core from which the AUTOSAR system is bootstrapped. |
Memory Protection Unit | A Memory Protection Unit (MPU) enables memory partitioning with individual protection attributes. This is distinct from a Memory Management Unit (MMU) that provides a mapping between virtual addresses and physical memory locations at runtime. Note that some devices may realize the functionality of an MPU in an MMU. |
Mode | Describes the permissions available on a processor. |
Privileged | In general, in »privileged mode« unrestricted access is available to memory as well as the underlying hardware. |
Non-privileged | In »non-privileged mode« access is restricted. |
Modulus | The number of ticks required to complete a full wrap of an OSEK counter. This is equal to OsCounterMaxAllowedValue +1 ticks of the counter. |
OS-Application | A collection of OS objects |
Trusted | An OS-Application that may be executed in privileged mode and may have unrestricted access to the API and hardware resources. Only trusted applications can provide trusted functions. |
Non-trusted | An OS-Application that is executed in non-privileged mode has restricted access to the API and hardware resources. |
OS object | Object that belongs to a single OS-Application: Task, ISR, Alarm, Event, Schedule Table, Resource, Trusted Function, Counter, Applicaton-specific hook. |
OS Service | OS services are the API of the operating system. |
Protection Error | Systematic error in the software of an OS-Application. |
Memory access violation | A protection error caused by access to an address in a manner for which no access right exists. |
Timing fault | A protection error that violates the timing protection. |
Illegal service | A protection error that violates the service protection, e.g. unauthorized call to OS service. |
Hardware exception | division by zero, illegal instruction etc. |
Resource Lock Time | The time an OSEK resource is held by a Task/ISR (excluding the preemptions of the Task/ISR by higher prior Tasks/ISRs). |
Response Time | The time between a Task/ISR being made ready to execute and generating a specified response. The time includes all preemptions. See Figure 2.1 |
Restart an OS-Application | An OS-Application can be restarted after self-termination or being forcibly terminated because of a protection error. When an OS-Application is restarted, the OS activates the configured OsRestartTask. |
Scalability Class | The features of the OS (e.g. Memory Protection or Timing Protection), described by this document, can be grouped together to customize the operating system to the needs of the application. There are 4 defined groups of features which are named scalability classes. For details see Chapter 7.11 |
Schedule Table | Encapsulation of a statically defined set of expiry points. |
Section | Part of an object file in which instructions or data are combined to form a unit (contiguous address space in memory allocated for data or code). A section in an object file (object file format) has a name and a size. From the linker perspective, two different sides can be distinguished: |
Input section | memory section in an input object file of the linker. |
Output section | memory section in an output object file of the linker. |
Set (of OS objects) | This document uses the term set, indicating a collection of the same type of OS objects, in the strict mathematical sense, i.e.: - a set contains zero or more OS objects (this means a set can be empty) - the OS objects in the set are unique (this means there cannot be duplicate OS objects in the set) |
Spinlock | A spinlock is a locking mechanism where the TASK waits in a loop ("spins") repeatedly checking for a shared variable to become a certain value. |
The value indicates whether the lock is free or not. In Multi-Core systems the comparison and changing of the variable typically requires an atomic operation. As the TASK remains active but is not doing anything useful, a spinlock is a busy waiting mechanism | |
Spinlock variable | A spinlock variable is a shared variable used by a spinlock to indicate whether a spinlock is free or occupied. |
Symbol | Address label that can be imported/used by software modules and resolved by the linker. The precise syntax of the labels is linker-specific. Here, these address labels are used to identify the start and end of memory sections. |
Start symbol | Tags the start of a memory section |
End symbol | Tags the end of a memory section |
Synchronization of schedule tables with a synchronization counter | Synchronization with a synchronization counter is achieved, if the expiry points of the schedule table are processed within an absolute deviation from the synchronization counter that is smaller than or equal to a precision threshold. |
Synchronization Counter | The “Synchronization Counter”, distinct from an OS counter object, is an external counter, external to the OS, against which expiry points of a schedule table are synchronized |
Task | A Task is the object which executes (user) code and which is managed by the OS. E.g. the OS switches between different Tasks (“schedules”). There are 2 types of Tasks; for more details see [15]. |
Basic Task | A Task which cannot block by itself. This means that it cannot wait for (OS) event(s). |
Extended Task | A Task which can block by itself and wait for (OS) event(s). |
Time Frame | The minimum inter-arrival time for a Task/ISR. |
Trusted Function | A service provided by a trusted OS-Application that can be used by other OS- Applications (trusted or non-trusted). |
Worst case execution time (WCET) | The longest possible execution time. |
Write access | Storing a value in a register or memory location. All memory accesses that have the consequence of writing (e.g. reads that have the side effect of writing to a memory location) are treated as write accesses. |

---|---|
Slot Delay | The time between start of frames in a schedule table. The unit is in number of time-bases for the specific cluster. |
Jitter | Difference between longest delay and shortest delay (e.g. Worst case execution time – Best case execution time) |
Maximum frame length | The maximum frame length is the TFRAME_MAX as defined in the ISO 17987-3 [19] (i.e. The nominal frame length plus 40 %). |
Schedule entry is due | This means that the LIN Interface has arrived at a new entry in the schedule table and a frame (received or transmitted) will be initiated. |
Slave-to-slave | From a LIN master node’s point of view, there exist 3 different directions of frames on the LIN bus: Response transmitted by the master, Response received by the master and Response transmitted by one slave and received by another slave. The slave-to-slave is describing the last one. This is not described explicitly in the ISO 17987 specifications, but mentioned in Figure 14 in ISO 17987-3: Three unconditional frame transfers. |
Irrelevant frame | From a LIN slave node point of view, there exist 3 different directions of frames on the LIN bus: Response transmitted by the slave, Response received by the slave and Response that is ignored by the slave (i.e. communication between master and another slave or between two other slaves). These ignored frames are named irrelevant frames in this specification. This is not described explicitly in the ISO17987 specifications. |
Relevant frame | From a LIN slave node point of view, a frame that is transmitted or received by the slave. Opposite of irrelevant frame. |
Sporadic frame | This is one of the unconditional frames that are attached to a sporadic slot. |
Sporadic slot | This is a placeholder for the sporadic frames. The reason to name it slot is that it has no LIN frame ID. |
Tick | The tick is the smallest time entity to handle the communication on all channels. |
Bus idle timeout | Lapse of time duration with no bus activity |

###2.2 Glossary
Besides AUTOSAR terminology this document also uses terms defined in the ISO 17987 specifications [16], e.g. LIN frame, header and message.
Glossary | Description |
---|---|
enumeration | This can be in “C” programming language an enum or a #define. |
LIN channel | The LIN channel entity interlinks the ECUs of a LIN cluster physically: An ECU is part of a LIN cluster if it contains one LIN controller that is connected to one LIN channel of the LIN cluster. An ECU is allowed to connect to a particular LIN cluster through one channel only. |
LIN cluster | As defined by [16]: “A cluster is the LIN bus wire plus all the nodes.” |
LIN controller | A dedicated LIN hardware with a build Frame processing state machine. A hardware which is capable to connect to several LIN clusters is treated as several LIN controllers. |
LIN frame | As defined by [16]: “All information is sent packed as frames; a frame consist of the header and a response.” |
LIN frame processor | Frame processing implies the complete LIN frame handling. Implementation could be achieved as software emulated solution or with a dedicated LIN controller. |

##2 Acronyms and abbreviations
Abbreviation / Acronym | Description |
---|---|
Activity state | The activity state is the status of a software component being executed. The activity state results from the permission state as a precondition and physical enable condition, too. It is not calculated by the FiM and not available as a status variable. It can only be derived from local information within a software component. For further details, see chapter 7.2.1.6. |
Functionality | Functionality comprises User-visible and User-non-visible functional aspects of a system (AUTOSAR_Glossary.pdf [2]). In addition to that - in the FiM context - a functionality can be built up of the contents of one, several or parts of runnable entities with the same set of permission / inhibit conditions. By means of the FiM, the inhibition of these functionalities can be configured and even modified by calibration. Each functionality is represented by a unique FunctionId. A functionality is characterized by a specific set of inhibit condition in contrast to runnable entities having specific scheduling conditions. |
Inhibition Condition | The relation between one FID, an inhibition mask and the status of a Dem event/component. (see FiMInhibitionConfiguration) |
Monitoring function | • Part of the Software Component. • Mechanism to monitor and finally to detect a fault of a certain sensor, actuator or could be a plausibility check • Reports states about events from internal processing of a SW-C or from further processing of return values of other basic software modules. • See also AUTOSAR_SWS_DiagnosticEventManager [3] |
Permission state | The permission state contains the information whether a functionality, represented by its FID, can be executed or whether it shall not run. The state is controlled by the FiM based on reported events. For further details, see chapter 7.2.1.6. |

Active Star (Network) | Star topology networks consist of one ore more active central nodes which rebroadcast(s) all transmissions received from a branch to all other branches on the network. All peripheral nodes may thus communicate with all others by transmitting to, and receiving from, the central node(s) if they are located on another branch. On detection of the failure of a branch the active star will isolate its peripheral nodes from all other branches resulting in fault confinement |
Branch | Element of an active star network topology sharing (i.e. electrically connected to) the same transmitter and receiver circuit on the physical layer. The failure of a branch will result in the isolation of its peripheral nodes by the active star from all other branches resulting in fault confinement. |
SPI/Spi Channel | A channel is a software exchange medium for data that are defined with the same criteria: configuration parameters, number of data elements with same size and data pointers (source & destination) or location. See specification of SPI driver for more details. |
SPI/Spi Job | A job is composed of one or several channels with the same chip select. A job is considered to be atomic and therefore cannot be interrupted. A job has also an assigned priority. See specification of SPI driver for more details. |
SPI/Spi Sequence | A sequence is a number of consecutive jobs to be transmitted. A sequence depends on a static configuration. See specification of SPI driver for more details. |
