Abstract

PURPOSE: To make easy for the content check of the main storage at the occurrence of failure, by constituting the system so that the channel unit can be transferred on the main memory unit for the content of main storage with the main storage damp instruction from CPU.
CONSTITUTION: In the data processing system performing the data processing process by the unit 4 and provided with CPU 1, main memory unit 2, channel unit 4 and a plurality of sub-channel units 5-0, 5-1...5-m, the unit 4 is provided with the sub-channel correspondence region corresponding to the sub-channel units 5-0, 5-1...5-m and the data buffer stack indicating the address information of the data buffer region prepared on the common control region unit 2. Further, the main storage provided with the command buffer region buffering the command from CPU 1 is provided and the unit 4 transfers the main storage content to the unit 2 with the direct memory access based on the main storage damp from CPU 1.
