Abstract: This paper provides a scheme of multi-processor embedded system simulation based on Instruction Set Simulator(ISS). By adopting interconnection based on bus and mechanism of sharing global memory, it can efficiently solve the problem of communication between processors. The global clock synchronization is introduced to realize flexibly the schedule for all processing units, which keeps the processors in step. Analysis show that the simulator can simulate and track one or more homologous object code which can also come from different sources.

Key words: embedded system, Instruction Set Simulator(ISS), multi-processor
