component Persistence & Memory
The S-Core Persistence & Memory component provides resilient non-volatile data storage, POSIX key-value storage databases, block storage interfaces, atomic file update mechanisms, and flash wear-leveling management.
Persistence Architecture & Key Requirements
| Requirement ID | Category | Safety / Security | Description |
|---|---|---|---|
feat_req__mem__key_value_store | Storage Engine | Safety: QM | Implements atomic key-value database storage with transaction support and automatic recovery from ungraceful power loss. |
feat_req__mem__block_storage | Block I/O | Safety: QM | Provides raw sector block access abstraction for mass storage partitions and high-frequency time-series logging. |
feat_req__mem__integrity_check | Data Integrity | ASIL B | Applies checksums (CRC-32 / SHA-256) to all persisted storage records and reports unrecoverable bit flips to health management. |
