WebThe gem5 simulator currently provides four di erent CPU models, each of which lie at a unique point in the speed-vs.-accuracy spectrum. AtomicSim- ple is a minimal single IPC CPU model, TimingSimple is similar but also simulates the timing of memory refer- ences, InOrder is a pipelined, in-order CPU, and O3 is a pipelined, out-of-order CPU model. WebThis repository contains scripts and microbenchmarks to generate a performance comparison between silicon statistics ( generated from perf ) and gem5 for a given set of microbenchmarks. The microbenchmarks are compiled and run on an ARM-based system, and the performance results are compared between perf and gem5 simulations.
How to access gem5 stats from the Python script?
WebDec 21, 2024 · void gem5::PowerState::computeStats ( ) Record stats values like state residency by computing the time difference from previous update. Also, updates the previous evaluation tick once all stats are recorded. Usually called on power state change and stats dump callback.
