Abstract
PURPOSE: To take out the desired memory location and the contents of the register from the outside, by providing the instruction generation part which generates the instruction for executing a program for debug, and also a switching means by which the generation part is connected to a computer of the dubug device by an output of the comparator.
CONSTITUTION: The debug device C having a dubug computer 5 is connected to the computer equipment A to be debugged. The programs required f r debugging such as a transfer program, etc. by which a data in DPU1 of the equipment A is transferred to CPU6 of the device C are stored in the common memory 12 of this device C. Moreover, an input unit 9 for inputting a data required for debugging, an output unit 10 for displaying a data which has been read out, and a latch circuit 17 for latching the address of the instruction required for dubugging are connected to the computer 5. And the equipment A is compared with the address of the circuit 17 by the comparator 18, the switching means 19, 20 are operated in accordance with the output of this comparator 18, and the instruction for executing the program of the memory 12 is output to the equipment A from the instruction generation part 16.
