Reliable embedded systems play an increasing role in modern life, especially in modern automotive designs. Many studies have proved that it performs better in many situations. Firstly, reliable embedded systems provide the system reliability improvements. Secondly, reliable embedded systems also can improve the development efficiency and make the development cycle shorter. However, in the high real-time required occasion, the software implementation of the RTOS can`t fully meet requirements. To have better real-time only through the algorithm improvement or just increase the processor speed. On the contrary, operating system based on a hardware implementation can make it more real-time and more reliable. The reason is due to that the hardware circuit is independent of the processor running and do not take up the processing time of the processor. Thereby it can save time to execute other tasks and improve real-time. In this paper, ARM+FPGA will be choose as the IP hardware development platform.
