Abstract
PURPOSE: To always execute a test program in an idle state to detect trouble in an early stage by checking the existence of following jobs at the time of terminating execution of the test program and executing the test program in case of the absence of following jobs.
CONSTITUTION: The test program is provided in a main storage device 10 of a system and is executed by central processing units 15-1 and 15-2. The access to the device 10 is controlled by a storage access control circuit 50 of units 15-1 and 15-2, and instruction prefetch and instruction code decoding are performed by an instruction prefetch control circuit 51. Various arithmetic processings are performed in an arithmetic circuit 52, and a microprogram is stored in a control storage 53, and the program is decoded by a control storage control circuit 57 to send a control signal to the circuit 52. The address of a test program storage address register 58 is used to issue the instruction read indication from the circuit 57 to the circuit 51, and the circuit 51 sends an instruction read request to the circuit 50 and reads out the instruction to execute the test program.
