Abstract
PURPOSE: To make an error indication by detecting a process lasting undesirably in a control program processing mode, only by adding a simple hardware constitution.
CONSTITUTION: The internal status information of CPU2 in the execution of a sequential data process is set to register 6and updated according to the progress of the process. Then, S and R indicate the stop and run modes of CPU respectively, and SUP the quality of a supervision. According to the progress of the process, instruction execution is controlled by program control word PSW. Mamely, the instructions are executed under the control of the program counter part, OS part indicating a supervisor mode or problem mode, and W part indicating whether CPU is in a run state or not. Once AND circuit 10 generates [1], it is counted up 8 and latched 9, so that an error indication will be made.
