PURPOSE:To input and output simultaneously data to and from a shared memory apparently and reducing data waiting states of respective processors, and improve the ability in decentralized processing by providing the shared memory with an address register and a data register for writing. CONSTITUTION:A processor when reading data out of the shared memory 4 outputs a readout address to a line 15 and reads the data from a line 14. At this time, a processor when writing data outputs a write address to a line 10 and the write data to a line 11. The write address is written in an address register 1 and the write data is written in a data register 2 respectively. Then when memory reading operation is completed, the write address is outputted to a line 5 and the write data is outputted to a line 6, so that the data is written in the memory 4. |
