• Fixed incorrect description of return value in Fee_InvalidateBlock and Fee_EraseImmediateBlock
用語(terms)
| term | Description |
|---|---|
| EA | EEPROM Abstraction |
| Address Area | Contiguous memory area in the logical address space Typically multiple physical memory sectors are combined to one logical address area. |
| EEPROM | Electrically Erasable and Programmable ROM (Read Only Memory) |
| FEE | Flash EEPROM Emulation |
| LSB | Least significant bit / byte (depending on context). Here, “bit” is meant. |
| Mem | Memory Driver |
| MemAcc | Memory Access |
| MemIf | Memory Abstraction Interface |
| MSB | Most significant bit / byte (depending on context). Here, “bit” is meant. |
| NvM | NVRAM Manager |
| NVRAM | Non-volatile RAM (Random Access Memory) |
| NVRAM block | Management unit as seen by the NVRAM Manager |
| (Logical) block | Smallest writable / erasable unit as seen by the modules user. Consists of one or more virtual pages. |
| Virtual page | May consist of one or several physical pages to ease handling of logical blocks and address calculation. |
| Internal residue | Unused space at the end of the last virtual page if the configured block size isn’t an integer multiple of the virtual page size (see Figure 3)). |
| Virtual address | Consisting of 16 bit block number and 16 bit offset inside the logical block. |
| Physical address | Address information in device specific format (depending on the underlying EEPROM driver and device) that is used to access a logical block. |
| Dataset | Concept of the NVRAM manager: A user addressable array of blocks of the same size. E.g. could be used to provide different configuration settings for the CAN driver (CAN IDs, filter settings, …) to an ECU which has otherwise identical application software (e.g. door module). |
| Redundant copy | Concept of the NVRAM manager: Storing the same information twice to enhance reliability of data storage. |
