Abstract
PURPOSE: To ensure the confirmation for not only the program error but for the interruption process situation by providing the program counter, the memory means and the output means to the processor and then reading out the contents of the counter when necessary.
CONSTITUTION: The contents of program counter 2 is delivered from counter 2 while the logic product is secured at AND gate 3 by the output of order decoder 1, and then memorized in exclusive memory device 4. Then the output from device 4 is supplied to output device 6 via output control circuit 5. Now, if the prescribed branch order plus the order to be executed next are decided, the output is produced at decoder 1 at the execution time of the branch order and the execution time of one order immediately after the branching. As a result, the address of the branch order plus the address of the order executed after the branch order are written into device 4 from counter 2 via gate 3, and the output is produced at device 6 in accordance with the output request given from circuit 5 for the confirmation.
