Abstract
A plurality of processors use a common memory under a time division control mode by way of a time division data bus. In the multiprocessor system, flip-flops are mounted for holding respective write permission flags. Also, a logic gate is employed, operative to allow the processor to write data in the common memory when both the write permission flag and the write request signal from the processor are generated simultaneously. Further, multiplexers are used so that the write operation can be achieved under the time division control mode.
