Abstract

PURPOSE: To secure any other operation on I/O bus to the auxiliary memory unit of a data processor even from a CRT display unit via a dedicated bus by relieving a burden upon the data processor by making the cross-call possible.
CONSTITUTION: Data processor 1 is composed of arithmetic controller 101, main memory 102 and channel unit 103; and unit 101 is connected to general I/O bus 2, where CRT display units 31...3n and other I/O units are connected. To channel unit 103, channel bus 4 is connected and to this bus 4, auxiliary memory unit 6 is connected by way of channel interface 51 and control circuit 52. Further, dedicated CRT bus 7 is connected to control circuit 52 through CRT interface 53 and bus 7 is units 31 and 3n, using unit 6, among units 31...3n. Then, it is made possible to call unit 6 even from units 31 and 3n via bus 7, thereby relieving a burden upon processor 1.
