Abstract

PURPOSE: To realize a multiple channel control system in which the allotment is never limited for the number of units of both the high-speed and low-speed units by securing the connection for each channel to either of the high-speed and low- speed units.
CONSTITUTION: Central process unit 1 possesses the following component parts: memory circuit 11 which can memorize that the varying speed input/output unit is under operation for the channel at the address corresponding to the channel; address register 12 which stores the channel numbers sent from channel control circuit 3 and then enables memory device 11 to perform the reading and writing in correspondence to the channels; and input/output command execution part 13 which gives supervisory to the start request given from control device 3 and then gives the start to the input/output command to be executed next. In case the input/output unit features a high speed, the high-speed process request information is sent from the input/output interface at the connection area between channel control device 3 and channel 4 with the input/output command start request given from device 3.
