PURPOSE:To raise the responsiveness and efficiency of a system, by connecting different kinds of computers by a direct memory access system. CONSTITUTION:The titled system is provided with a direct memory access (DMA) bus 1, and a host computer 2 and a slave computer 3, having main memories 2M, 3M, which are both connected to said bus 1. Also, it is provided with a memory control means 4 which is started by one computer and transfers a data stored in the main memory of one computer to the main memory of the other computer through said but 1 by means of DMA. In this way, for instance, a processor part 2P of the host computer 2 sets a data to the transferred, to the memory part 2M, and sends a data transfer request to a processor part 3P of the slave computer 3 through an interruption control device 8. The processor part 3P which has received this request starts the device 4, and the device 4 transfers a data of the memory part 2M to the memory part 3M through the bus 1. |
