Abstract

PURPOSE: To make the data processing system diagnosis for small-size devices possible without increasing hardware except a processor by providing the service processor provided with a data processor part, a data storage part and a self-chcek part.
CONSTITUTION: Service processor 8 is connected to the service processing system provided with main memory 4, CPU1, channel 5 and I/O devices 6W6". This processor 8 is provided with microprocessor 9, memory 10 constituting a memory part, ROM11, display part 12 as a self-check part and switching circuit 13, and further, CPU1, is divided into plural units. Diagnosing data is entered from processor 8 to a FF and a register in every unit of CPU1, and after that, states of the FF and the register and read out through microprocessor 9 to cause channel 5 and devices 6W6" to execute prescribed processings, and the system is diagnosed on a basis of the state for every CPU1, processed information and information stored previously.
