Design and Application of software timer in W indows Operating System

Abstract: In order to realize accurate timing of computer software, a high-precision microsecond-level timer is designed. The timer uses the high-precision counter of the computer to complete the timer function. The timer precision on the pentiurn 1 V computer on the Great Wall can reach dozens of microseconds. To test the performance of this high-precision timer, a control program based on Windows multithreading mechanism is developed using Visual C
