At the OP code change time, the respective values are latched in registers 3, 5. Since the value of the counter having been latched in the register 5 at the previous OP code change time is held in a register 6, the execution time of the command of the previous time is obtained by simply subtracting the values of the both in an arithmetic circuit 7. By writing the value of a register 8 in which the OP code of the previous time is latched and the value of this arithmetic circuit 7 into a memory 4, the execution time of the respective commands may be measured.
