Abstract

PURPOSE:To realize the connection to an external device having an interface incompatible with existing channel devices by using an interface which performs the transfer of data, a means which performs the transfer of control signals, and a means which performs the transfer of data to and from a memory. CONSTITUTION:A channel device interface part 3 is connected to a channel device of the existing information processor at the side of an input/output device and performs the transfer of a start signal and the signal of a control system for interruption request, etc. A memory interface part 2 is connected to a memory access system of the existing information processor and performs the direct transfer of data to and from the memory. An external device interface part 4 is connected to an external device 6 and controls the transfer of data to and from the device 6. These interface parts 2-6 are controlled by a common control part 5. In such constitution, the connection is secured to the device 6 of high transfer speed which contains an interface different from an input/ output interface of the information processor. Thus the transfer of data is controlled between the main memory of the existing information processor and the device 6.
