Performance●CPU performance equation●Benchmarks: programs that allow you to getperformance measurements by simulating reallifeworkloads●Geometric mean used to average unitlessbenchmark results, otherwise, use arithmetic mean
Pipelining●●●Split an instruction in multiple consecutive stageswhich can be overlapped. Multiple instructions arein a different stage of execution at any given timeN-stage pipeline means overlapped execution of Ninstructions. Ideal speedup=N.Never ideal!●●●New delays introduced by pipelineHazards: structural, data, controlOthers: memory contention, pipeline imbalance
