Abstract：In the faceofcomplexembedded systemsapplied intheaerospacefield，the traditional embedded development method may have problems such as hardware development restricting software development and hardware resource shortage. The simulation environmentofthetarget hardware platform isconstructedbyvirtualizationtechnology，whichcansimulate the keycomponentssuchas CPU，memoryandI/Odeviceofthe target hardware，sothatdeveloperscanstillcarryout the developmentofembeddedsoftwareintheabsenceofactualhardwareresources.Thisresearchmainlyfocusesontheconstruction of the mnimal SoC modelofacertain typeof multi-core processor.Combined withthe processor's data manualand QEMU related knowledge，thevirtualizationoftheCPUcoreoftetargetsimulatorisrealized.Atthesametie，itcovers tepriperal hardwaresimulationcloselyrelated toit，incudingtheprocessor's memory，interruptontroler，inputandoutputdevics，etc. Theeffectivesimulationofthesehardwareisanimportantfactortoensurethestableoperationofthevirtualsimulationplatform.
