Abstract

PURPOSE: To simplify the unit by removing the control-word discrimination unit by storing a buffer register with an answer signal and operation end signal from an input-output unit and by interrrupting a channel unit by a required operation end signal obtained through classification by flag bits.
CONSTITUTION: Data channel unit DCH and input-output unit IOC1 to IOCn different in interface are connected to interface converter circuit IFC, which is provided with buffer registers BR1 to BRn stored with control word C and control- word discrimination flag bit F discriminating the kind of the control word. Then, control ward C is given discrimination flag bit F by unit DCH and sent to registers BR1 to BRn, where it is stored. Answer signals and operation end signals from units IOC1 to IOCn which correspond to control C and flag bit F stored in registers BR1 to BRn are discriminated by AND gate AG and OR gate OR and required signals are supplied to unit DCH as the operation end signals.
