Abstract
By introducing the function of the task delay in μC/OS - II real time system, task delays' strengths and weaknesses in the system are analyzed. For task delay has taken to processor time about the total numbers of task problems and scanned the task has significant processor time problems. The task delay mechanism in the operating systems is improved. Improved system is tested on the second generation Cortex-M3 LPC1768 processor. Software simulation shows that this method can improve the system real time performance and lower the overhead costs.关键词
