Abstract
PURPOSE: To shorten the time of debugging by executing instructions when control over program processing is transferred from a program to be debugged to the other and then by advancing the program, instruction by instruction, when the control returns to the program to be debugged.
CONSTITUTION: Once debugging indication information is input from console input part 3, instruction cycle assigning flip-flop (FF)A, mode setting FFs B and C and FFs for comparison information bits R1 and R2 are put into operation. As an opera- tor indicates the start of a program, an instruction is read out of a memory and tranferred to register information bit parts P1 and P2, whose outputs are compared by comparing circuits C1 and C2. Consequently, whether the program is that to be debugged or not is decided. When neighter FFB nor C is in operation while FFA is in operation, results of comparing circuits C1 and C2 are invalidated and an instruction run mode is validated.
