Performance Tuning and Signoff: Design Space
Design Space for Performance Tuning and Signoff.
Design space
Design Space for Performance Tuning and Signoff is anchored on P95 and P99 workload latency, sustained throughput per subsystem, and power-performance target closure against signoff criteria.. 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.
