用語(terms)
| Term | Description |
|---|---|
| Basic Storage Object | A "Basic Storage Object" is the smallest entity of a "NVRAM block". Several "Basic Storage Objects" can be used to build a NVRAM Block. A "Basic Storage Object" can reside in different memory locations (RAM/ROM/NV memory). |
| NVRAM Block | The "NVRAM Block" is the entire structure, which is needed to administrate and to store a block of NV data. |
| NV data | The data to be stored in Non-Volatile memory. |
| Block Management Type | Type of the NVRAM Block. It depends on the (configurable) individual composition of a NVRAM Block in chunks of different mandatory/optional Basic Storage Objects and the subsequent handling of this NVRAM block. |
| RAM Block | The "RAM Block" is a "Basic Storage Object". It represents the part of a "NVRAM Block" which resides in the RAM. See [SWS_NvM_00126] |
| ROM Block | The "ROM Block" is a "Basic Storage Object". It represents the part of a "NVRAM Block" which resides in the ROM. The "ROM Block" is an optional part of a "NVRAM Block". [SWS_NvM_00020] |
| NV Block | The "NV Block" is a "Basic Storage Object". It represents the part of a "NVRAM Block" which resides in the NV memory. The "NV Block" is a mandatory part of a "NVRAM Block".[SWS_NvM_00125] |
| NV Block Header | Additional information included in the NV Block if the mechanism "Static Block ID" is enabled. |
| Administrative Block | The "Administrative Block" is a "Basic Storage Object". It resides in RAM. The "Administrative Block" is a mandatory part of a "NVRAM Block". [SWS_NvM_00135] |
| DET | Default Error Tracer - module to which development errors are reported. |
| DEM | Diagnostic Event Manager - module to which production relevant errors are reported |
| NV | Non volatile |
| FEE | Flash EEPROM Emulation |
| EA | EEPROM Abstraction |
| FCFS | First come first serve |
