PROBLEM TO BE SOLVED: To provide a simulator for verifying coordination between hardware and software based on a SystemC simulator capable of reducing processing time by reducing the overhead of context switching control. SOLUTION: The simulator is provided with time keepers for controlling the simulation times of a plurality of threads generated as simulation models of hardware and software. Each of the time keepers 12 has a variable X for retaining the simulation time Tsim of each thread, a variable Y for retaining integrated time Tsum, and an interrupt request queue Q for storing an interrupting method corresponding to interruption time, manages variables x, y and the queue Q according to six kinds of method calls from the threads, and calls the wait function of the SystemC simulator 11 if necessary. In this way the number of times that the wait function is called is reduced and the overall processing time can be reduced. COPYRIGHT: (C)2008,JPO&INPIT
