PURPOSE:To perform processes in parallel by processors in point of time respectively, by providing a shared memory so that a read only state is introduced by the processor on one side, and a write only state, by the processor on the other side. CONSTITUTION:A processor 1, when sending a bit of information to a processor 2, writes the fact on a flag setting part 8 after writing the bit of information on a shared memory 7-1. The processor 2 reads the content of the setting part 8, and reads the bit of information in the memory 7-1 based on the content. Adversely, when the processor 2 sends out the bit of information to the processor 1, it writes the fact on the setting part 8 after writing the bit of information on a shared memory 7-2. The processor 1 writes the content of the setting part 8, and reads the bit of information based on the content. In this way, respective processor can perform the process in parallel in point of time. |
