ABSTRACT:
A data transfer system in a device control apparatus for controlling data transfer between a channel of a central processing unit and a device, comprising: a channel transfer circuit for transferring data to the channel and for receiving data from the channel; a device transfer circuit for transferring data to the device and for receiving data from the device, and an intermediate memory for temporarily storing transfer data from the channel or from the device transfer circuit only when the transfer rate determined by the channel is different from the transfer rate determined by the device.
