Abstract

See full text

Branch sequences for branch prediction performance test are generated by performing the following steps: (i) generating a branch node graph, by a branch node graph generator machine logic set, based, at least in part, upon a set of branch traces of a workload or benchmark code; (ii) generating a first assembly pattern file, for use with a first instruction set architecture (ISA)/microarchitecture set, by an assembly pattern generator machine logic set, based, at least in part, upon the branch node graph so as to mimic the control-flow pattern of the workload or benchmark code; and (iii) running the assembly pattern file on the first ISA/microarchitecture set to obtain first execution results.
