Pipeline timing analysis using a trace-driven simulator
Jakob Engblom, Andreas Ermedahl · 2003
We present a technique for worst-case execution time (WCET) analysis for pipelined processors. Our technique uses a standard simulator instead of special-purpose pipeline modeling. Our technique handles CPUs that execute multiple shorter instructions in parallel with long-running instructions. The results of other machine analyses, like cache analysis, can be used in our pipeline analysis. Also, results from high-level program flow analysis can be used to tighten the execution time predictions. Our primary target is embedded real-time systems, and since processor simulators are standard equipment for embedded development work, our tool will be easy to port to relevant target processors.
