OSEK COM およびAUTOSAR COM
OSEK/VDX Communication Version 3.0.3
INTERACTION LAYERという名前は OSEK/VDX COMから来ている。
OSEK Table 2-1: Message filter algorithms
| Algorithm Reference | Algorithm | Description |
|---|---|---|
| F_Always | True | No filtering is performed so that the message always passes |
| F_Never | False | The filter removes all messages |
| F_MaskedNewEqualsX | (new_value&mask) == x | Pass messages whose masked value is equal to a specific value |
| F_MaskedNewDiffersX | (new_value&mask) != x | Pass messages whose masked value is not equal to a specific value |
| F_NewIsEqual | new_value == old_value | Pass messages which have not changed |
| F_NewIsDifferent | new_value != old_value | Pass messages which have changed |
| F_MaskedNewEqualsMaskedOld | (new_value&mask) == (old_value&mask) | Pass messages where the masked value has not changed |
| F_ MaskedNewDiffersMaskedOld | (new_value&mask) != (old_value&mask) | Pass messages where the masked value has changed |
| F_NewIsWithin | min <= new_value <= max | Pass a message if its value is within a predefined boundary |
| F_NewIsOutside | (min > new_value) OR (new_value > max) | Pass a message if its value is outside a predefined boundary |
| F_NewIsGreater | new_value > old_value | Pass a message if its value has increased |
| F_NewIsLessOrEqual | new_value <= old_value | Pass a message if its value has not increased |
| F_NewIsLess | new_value < old_value | Pass a message if its value has decreased |
| F_NewIsGreaterOrEqual | new_value >= old_value | Pass a message if its value has not decreased |
| F_OneEveryN | occurrence % period == offset | Pass a message once every N message occurrences.Start: occurrence = 0.Each time the message is received or transmitted, occurrence is incremented by 1 after filtering.Length of occurrence is 8 bit (minimum). |
ISO OSEK/VDX と AUTOSARの大きな違いを４つあげれば、
AUTOSAR はOSを拡張している。
COMとNMが違う。
RTEを定義している。
OIL(OSEK Implementation Language)ではなくARXMLで幅広い設定ができる。
| Function | ISO OSEK/VDX | AUTOSAR |
|---|---|---|
| Filter | 定義 | 参照 |
| VFB | COM | RTE |
COMの違いは、RTEを定義していることにもよる。
それ以外にも、AUTOSARにはISO OSEK/VDXにない機能がいろいろあるが、
OS、COM、NMが関係しているのは
Abstract Platformとの関係
ISO 各種規格に基づいた診断、通信の抽象的な定義をする。
必要があれば国際規格を改定する。

用語(terms)
| Term | Description |
|---|---|
| I-PDU | Interaction Layer Protocol Data Unit (assembled and disassembled in AUTOSAR COM), consists of one or more signals (see below and [DOC_LAYER]). |
| I-PDU group | An I-PDU Group is an arbitrary collection of I-PDUs of the same direction (i.e. send or receive) in COM |
| LOM | Listen Only Mode |
| L-PDU | Data Link Layer Protocol Data Unit (assembled and disassembled in AUTOSAR Hardware Abstraction layer, see [DOC_LAYER]). |
| signal | A signal in the AUTOSAR COM context is equal to a message in [DOC_ISO_COM]. An AUTOSAR signal is carried by one or more signals in COM. The transformation from an AUTOSAR signal to a signal in COM is carried out by the RTE. Typically the transformation preserves the syntax of the data. However, in the case of complex data types the transformation may change the syntax of the signal. Therefore a signal in AUTOSAR COM is not always the same as an AUTOSAR signal. |
| signal group | A signal group refers to a set of signals that must always be kept together in a common I-PDU. A Signal group is used to guarantee the consistent transfer of AUTOSAR composite data types. A signal group has the following properties: - A signal can belong to at most one signal group - A signal group can not belong to more than exactly one I-PDU - Signal groups do not overlap each other within an I-PDU - Signal groups are a contiguous set of signals which belong to this group, however it is possible to have unused bits (“holes”) within a group. - Signal groups may contain no signals (“may be empty”). The grouping of signals to signal groups is assumed to be provided as an input for the COM generation process. |
