Abstract

PURPOSE: To easily recognize the status in use of a microprogram, by storing the microprogram in a medium such as a main storage part, etc., after attaching an ECC pattern which becomes one bit error in advance, and saving the microprogram designated as the object of overlay, and to be read out.
CONSTITUTION: An error correction code which becomes the one bit error is attached in advance on each word of the time microprogram, and it is stored in the storage medium. At time of a test mode, after the microprogram is moved from the storage medium to a control part 1, the program is executed correcting the one bit error for each word of the microprogram, and rewriting it on the control storage part 1, and an overlay module which becomes the object of the control storage part 1 is moved to the saving area of the above stated storage medium corresponding to the generation of the overlay.
