A Novel Implementation of Hardware Based Hybrid Embedded RTOS

摘要

Reliable embedded systems play an increasing role in modern life, especially in modernautomotive 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 thedevelopment cycle shorter.However, in the high real-time required occasion, the software implementation of the RTOScan`t fully meet requirements. To have better real-time only through the algorithm improvementor just increase the processor speed. On the contrary, operating system based on a hardwareimplementation can make it more real-time and more reliable. The reason is due to that thehardware circuit is independent of the processor running and do not take up the processing timeof the processor. Thereby it can save time to execute other tasks and improve real-time. In thispaper, ARM+FPGA will be choose as the IP hardware development platform.
