Vector Lanes and Chaining: Design Space
Design Space for Vector Lanes and Chaining.
Design space
Design Space for Vector Lanes and Chaining is anchored on Cycles-per-element for dependent vector pipelines under lane-count, memory-bandwidth, and chaining-depth constraints.. 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.
