Expand description
Cached-key, fixed-64-byte Ed25519 signing pipeline.
The pipeline holds 128 independent requests and schedules their three SHA-512 blocks, scalar reductions, fixed-base multiplications, paired point compression, and scalar multiply-add operations independently. Messages and intermediate values live in inferred BRAM; no DRAM, HBM, or host prehash is part of the cryptographic path.
