Abstract: Nogoodbenchmarksuitewasmadetoevaluatethedetectionmethodsortoolsfortheadventofinterruptdatarace.Basedontherealaerospaceembeddedsoftwaredataracebugs，sixessentialfactorsrelatedtodataracedetectionwereproposed，andthedataracebenchmarksuitenamedRaceBenchforaerospaceembeddedsoftwarewasdesigned.TheRaceBench，whichisclosetorealprogramsandisextensible，coversallsixfactors.TheRaceBenchwasusedtoevaluateadataracedetectiontoolnamedSpaceDRC.TheresultshowsthatRaceBenchcanevaluatethecapabilitiesofthetooleffectively.
