Abstract
PURPOSE: To enable the continuity of job through immediate correction of bit error, by monitoring the loading of microprogram and writing in the correction bit data to the control memory of processor at error bit detection.
CONSTITUTION: The data in the floppy disc 1 is loaded to the control memory 4 of processor via the address register 3 with the loader 2 including the monitor. Further, when error bits are detected at the parity check circuit 7, the error correction circuit 8 retrieves the address of the memory 4 producing the bit errors and picks up the instruction corresponding to the address from the disc 1 for inverted bit processing, then the bit data in the memory 4 is rewritten for the correction. Accordingly, the error of the control memory is immediately corrected and the job by the processor can be continued.
