PMEvo: Portable Inference of Port Mappings for Out-of-Order Processors by Evolutionary Optimization [article]

Fabian Ritter, Sebastian Hack
2020 arXiv   pre-print
This ability is determined by the port mapping of the processor, which describes the execution units of the processor for each instruction.  ...  Furthermore, it finds port mappings for AMD's Zen+ architecture and the ARM Cortex-A72 architecture, which are out of scope of existing techniques.  ...  We evaluate PMEvo by the throughput prediction accuracy of its inferred port mappings on port-mapping-bound basic blocks for microarchitectures by Intel, AMD and ARM.  ...
