ABSTRACT:
A peripheral controller capable of simultaneously handling data transfer microprocesses for several different peripheral devices. The controller includes a set of memories, logic circuits and a physical interface channel for transmitting data between a control processing unit and the peripheral controller and for transmitting data between the peripheral controller and the peripheral devices, an interface control unit for enabling a predetermined one of the peripheral devices to communicate with the peripheral controller, a memory for storing microprograms for controlling the data flow between the control processing unit and the peripheral devices, and a processing circuit for administering the sharing of the processing time of the peripheral controller between the plurality of peripheral devices and the control processing unit.
