PROBLEM TO BE SOLVED: To prevent the competition of buses between processors even when each of processors accesses a kernel and the task information of an execution task. SOLUTION: The bus configuration of a system is made into two stages of a local bus 15 and a global bus 16, two kinds of memories of private memory 11 accessible only for a present processor and a shared memory 12 commonly accessible even from the other processors are loaded on the local bus 15 of each of processors 1-3, a kernel part is loaded in the private memory 11 and a task information part is loaded in the shared memory 12. Thus, even when each of processors 1-3 accesses the kernel and the task information of the execution task, the competition of buses between processors can be prevented. Further, by performing task scheduling while referring to a data transfer time table, the data transfer time of task information between processors can be shortened.
