Abstract
PURPOSE: To easily execute the debug of the microprogram and the operation confirmation of the 1-chip CPU, by the program level, by controlling the microprocessor by the specific micro-instruction from the micro-instruction generation means.
CONSTITUTION: This device is equipped with the integrated 1-chip micro (μ) processor 11 and the ROM12 which has stored various μ programs containing the specific test program. Also, the specific instruction for designating the branch to the specific program is generated from the μ instruction generation part 18, and the specific address is set to the address register 14. The contents of this register 14 are compared with the address submitted to the ROM12 from the processor 11 by the comparator 15, the read-out output of the ROM12 is inhibited by the coincidence output from this circuit 15, the μ instruction is sent out to the processor 11 from the generation part 18 by the D type FF17, it is made to branch to the specific test program designated by the μ instruction when coincidence by the circuit 15 has been detected, and the operation confirmation of the processor 11 is executed easily by the program level.
