With the growing design complexity of contemporary embedded systems, real-time operating systems (RTOSs) have become one of important components of such complex embedded systems. This paper presents an RTOS-centric hardware/software cosimulator which we have developed for embedded system design. One of the most remarkable features in our cosimulator is that it has a complete simulation model of an RTOS which is widely used in industry, so that application tasks including RTOS service calls are natively executed on a host computer. Our cosimulator also features cosimulation with functional simulation models of hardware written in C/C++ and cosimulation with HDL simulators. A case study with a JPEG decoder application demonstrates the effectiveness of our cosimulator.
