Title: Improvement of μC/OS-II based on HCS12X Series Dual-core Microprocessor
Abstract: μC/OS-Ⅱ operating system is widely used in embedded system real-time operating system,but now μC/OS-Ⅱ is for the transplantation application based on single-core processor.For microprocessors with a co-processor,μC/OS-Ⅱ operating system can not give full play to the performance of improving the system in real time.The structure of microprocessors with a co-processor was studied,by modifying the micro-kernel architecture,coprocessor handled the μC/OS-Ⅱ clock interrupt to reduce the micro-kernel running time in the main CPU kernel and improve the system in real-time.Through the analysis after experiments with MC9S12XEP100 chip,it proved that this method is feasible.
