PURPOSE:To transfer data at a high speed by securing the optional connection between plural microprocessors and memory parts of the same number as those microprocessors with the open/close control for the cross points of data buses arrayed in a grid form. CONSTITUTION:Microprocessors 11-13 and memory parts 21-23 are connected to data buses 41-43 and 51-53 which are arrayed in a grid form. Then these microprocessors can be optionally connected to the memory parts by opening and closing the cross point switches 611-613, 621-623, 631-633, etc. In a data writing mode, the data is transferred simultaneously to plural memory parts from a microprocessor. When the data of each microprocessor is used, one among the memory parts is used as an exclusive memory part to read the transfer data. |
