Detailed Description
Generic FIFO queue implementation for embedded safety-critical use.
- Version
- 1.0.3
- Date
- 2025-11-06
Provides deterministic enqueue/dequeue operations on a caller-supplied memory buffer. Implementation uses explicit byte-wise copying and avoids standard library dependencies to ensure predictable timing.
MISRA Deviation: DV-QUEUE-001 (Rule 11.4) Controlled cast from void* to uint8_t* for raw byte access. Safe because data is not type-reinterpreted.
