Abstract

PURPOSE: To display the function of debugging a program easily and efficiently by outputting an interruption signal when the contents of a debugging register in which a random value can be set externally are compared to those of an instruction code register.
CONSTITUTION: The instruction code of an instruction to cause an interruption is written in debugging register 12 externally. After the program is executed and an instruction with the same instruction code as that stored in register 12 is executed, the instruction code is stored in instruction code register 11 and this is compared to the code in register 12 by comparing circuit 13, so that when the both agree with each other, an interruption signal will be sent out via signal line 53 to cause the interruption. Corresponding to this interruption, the contents of the register and memory needed for program debugging are read out and modified. Consequently, debugging comes into effect easily at a point in time in the process of the processing.
