Abstract
PURPOSE: To automatically restore the memory error, by reloading the processing program when the memory error in the processing program is detected.
CONSTITUTION: In the program control unit, the processing program is stored in the RAM part of the control memory and ROM part contains the load program and the test program. At the execution of processing program, the error control section is taken as the normal mode 5 and the clock is stopped at the production of error. At the execution of test program, the error control is taken as inhibit mode to inhibit the stop of clock other than error at memory readout, and the fact of error detection only is stored to keep the execution. Further, if error is present, the load program is executed and branched at the head of the processing program. After that, the executions 5W13 of the processing program and the test program are repeated.
