Expand description

Platform-specific timing parameters for WCET calculation.

Must be characterized via hardware profiling (Genchi Genbutsu).

§Safety Note

These values represent worst-case performance. Actual execution will typically be faster. Use these for real-time deadline guarantees.

Fields§

§min_read_speed_mbps: f64

Minimum guaranteed read speed from storage (MB/s) Account for worst-case fragmentation and bus contention

§min_decomp_speed_mbps: f64

Minimum decompression throughput (MB/s uncompressed output) Zstd has bounded worst-case

§crc32_throughput_mbps: f64

CRC32 throughput using hardware acceleration (MB/s) Most ARM cores: ~2000 MB/s with CRC32 instruction

§ed25519_verify_us: f64

Ed25519 signature verification time (microseconds) Constant time regardless of message size

§deserialize_throughput_bps: f64

Bincode deserialization overhead (bytes/μs)
