Abstract

PURPOSE: To make it possible to execute an error countermeasure proessing efficiently by causing a request source processing unit, which requests a processing, to instruct previously the countermeasure at an error occurrence time and requesting the processing to the execution processing unit side.
CONSTITUTION: Central processing unit 1 prepares channel address word (CAW) 8 on main memory 2 and issues start I/O command 6 to channel controller 3. Channel controller 3 accepts command 6 and reads CAW 8 on the main memory and informing channel unit 4-0 to start a specific I/O device, for example, 5-0. Data communication is performed between I/O device 5-0 and the data buffer part on main memory 2 through channel unit 4-0 and channel controller 3. Error processing fields b0 to b2 are pepared in command 6, and an error processing countermeasure is instructed when central processing unit 1 issues command 6.
