<p>PURPOSE: To provide a multiprocessor device which can write data in the main memories of other processors without decreasing the total throughput of the multiprocessor device. CONSTITUTION: This multiprocessor device has a cache memory 5-1 and a write control circuit 6-1 which controls data writing to the cache memory 5-1, and the write control circuit 6-1 writes the same data as data written in a main memory 3-1 from a CPU 2-1 in the cache memory 5-1, and when a system bus 10 is in use, the written data are held as they are, and when the system bus 10 is free, the written data are written in the main memories 3-1 to 3-N of other all processors 1-2 to 1-N.</p> |
