PROBLEM TO BE SOLVED: To provide the emulator which can obtain the execution state of a subroutine in real time without stopping the execution of a target program. SOLUTION: When the emulator is formed including a system bus 12 which can gather target program execution information of an emulation microprocessor, a 1st counter 23 which measures the execution times of subroutines included in the target program and a 1st register 25 which is coupled with the system bus 12 and can hold the count value of the 1st counter 23 are provided to relax restrictions of the timing of direct output of the count value of the 1st counter 23 to the system bus 12. |
