RVV Vector Basics: Design Space
Design Space for RVV Vector Basics.
Design space
Design Space for RVV Vector Basics is anchored on Sustained vector utilization across mixed-width kernels while keeping scalar fallback correctness intact.. 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.
