辺装置制御システム。In a peripheral device control system that controls input/output of peripheral devices via a CPU bus under the supervision of a CPU, a DMA device and an external buffer device are connected to the CPU bus, and a DMA device and an external buffer device are connected to the external buffer device via an external bus. devices are connected, and input data corresponding to each peripheral device is transferred to the external buffer device by the DMA device.
MA transfer is performed, and when the transfer of input/output data to the external buffer device is completed, information other than the data, such as whether transfer processing can be performed and the amount of data for each peripheral device, is transferred from the external buffer device to the CPU as interrupt data.
