Abstract

PURPOSE: To improve versatility in case of use of CPU by enabling a single input- output device by several pulses from certain CPU to control the operation of an interface provided in a dynamic change-over unit while disabling other CPU from controlling it.
CONSTITUTION: Interfaces A1 and B1, and A2 and B2 of input-output devices IOCIand IOCII are connected to channels K and L, and M and N of CPU0 and CPU1 via buses 1 and 2, and 3 and 4, and devices IOCI and IOCII are connected to dynamic change-over unit DCS. To change-over unit DCS, input- output devices IOl to IOn are connected, devices IOCI and IOCII are not given information on a cross call at all, and change-over units DCS are provided with CPU0 and 1 a processor for reserve information on a unit to realize the operation over the control of devices IOl to IOn, so that versatility at the time when CPUs 0 and 1 are used will be improved.
