PURPOSE:To perform easily appreciation with small deviation by storing successively microinstruction address corresponding to the address number of a memory for measuring, and measuring the microinstruction address dispersedly while counting the number of times of storing. CONSTITUTION:The computer appreciating device is provided with a trigger signal generating circuit 1, memory for measuring 2, memory address register for measuring 3 and an adder 4. Microinstruction address is read out from a microinstruction address register 7 each time trigger signal having random period is generated, and stored in the memory 2 for measuring. The adder 4 counts the number of times of storing, and when the number of times of storing arrives at preset number of times, and microinstruction code stored in the memory 2 for measuring overflows, this is detected and sending out of the adder output is stopped or stopped and additing action is brought into waiting state until next measuring. |
