Abstract
PURPOSE: To make it possible to retry the processing of an error without reducing a processing speed by performing the retry by resetting information in a main memory by analyzing error information by an error processing program.
CONSTITUTION: An error processing microprogram is provided onto line 33 and an update inhibition signal is generated on line 34. After the execution of micro instructions (MT14) is inhibited, the microprogram is branched to the error processing microprogram according to a start address from address control circuit 32. Through the error processing program, error information is analyzed, information in the main memory is reset and the retry instruction is executed in step 11. Then, the control is returned to the micro instruction in step 14 assigned by the held address to execute the interrupted microprogram normally. Thus, the processing of the error can be retried without reducing the processing speed.
