Five-Stage Pipeline Partitioning and Timing Contracts: Step-by-Step Walkthrough

Step-by-step walkthrough

Step-by-Step Walkthrough for Five-Stage Pipeline Partitioning and Timing Contracts is anchored on Post-layout Fmax versus stage slack spread, plus bubble rate introduced by stage-boundary timing fixes.. Convert observations into mechanism-backed decisions with explicit ownership.

1. Define failing workload and acceptance threshold.

2. Capture reproducible metadata and evidence snapshot.

3. Classify dominant mechanism path.

4. Propose minimal reversible change.

5. Validate cross-workload and corner behavior.

6. Document owner and rollout decision.

               +-> branch resolve + redirect

Hot paths:
  - branch + load-use dependencies in ID/EX
  - memory latency stretching MEM stage
  - writeback arbitration for integer/vector units

Focus: keep control hazards predictable
