Abstract
The real-time operating system(RTOS) simulator, one of the tools provided by RTOS development environment, allows users to develop and debug application programs even before the target hardware is ready. Thus, most of commercial RTOS development environments provide with RTOS simulator for the purpose. But they are implemented to simulate only functional aspects on a host system, so that it is not possible to estimate execution time of application programs on the target hardware. Since the real-time system has to complete program executions in predetermined time, the RTOS simulator that can estimate the execution time is yeW useful in the development phase. In this study, we develop a machine instruction-level RTOS simulator that is able to estimate execution time of application programs on a target hardware, and prove its functionality and accuracy by using test .programs.
