Base Integer ISA (RV32I and RV64I) Execution Model: Design Space
Design Space for Base Integer ISA (RV32I and RV64I) Execution Model.
Design space
Design Space for Base Integer ISA (RV32I and RV64I) Execution Model is anchored on Instruction count mix, branch density, and CPI breakdown by ALU, load/store, branch, and control-transfer classes.. 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.
