Compressed ISA and Extension Landscape Overview: Design Space
Design Space for Compressed ISA and Extension Landscape Overview.
Design space
Design Space for Compressed ISA and Extension Landscape Overview is anchored on Code-size reduction from C extension, extension utilization rate, and performance-per-watt impact by workload segment.. 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.
