Bitmanip and Crypto Extensions: Design Space
Design Space for Bitmanip and Crypto Extensions.
Design space
Design Space for Bitmanip and Crypto Extensions is anchored on Latency and throughput for SHA/AES/SM primitives versus scalar baselines, with constant-time behavior validation.. Convert observations into mechanism-backed decisions with explicit ownership.
Trade latency and throughput against power and area.
Prefer architecture options with clear software contract impact.
Quantify extension-profile cost before enabling by default.
Keep bring-up and validation ownership explicit.
