Abstract

PURPOSE: To enable the operation as if direct access were made by program, by requesting the access of the program non accessible memory unit to the console control unit with the "request instruction".
CONSTITUTION: When the "request instruction" is set to the instruction register 4, the instruction is decoded 5, and the address information in it is transferred to the console control unit 2 via the gate 6 to stop the clock of the data processing unit 1. Further, the unit 2 transfers the address information transferred to the diagnostic processing address decoder 3 via the means 8 the decoder 3 accesses the program non accessible memory unit MMo based on the address information to execute scan- out, the data is transferred to the unit 2 via the means 9, and the unit 2 transfers the content on the program accessible memory unit MM1 of the unit 1 via the data informing means 10. That is, since the content of MM0 is copied on MM1, the unit 1 can read the content of MM1 with instruction.
