摘要
针对节点操作系统的特点及其对实时性、安全性、并发性的要求,提出一种新的实时系统内核调度算法,通过将任务优先级调度和时间片轮询相结合,提高处理器的响应速度,改善系统的实时性。将该调度策略在μCOS-II上进行实现,并将修改后的内核应用于无线采集系统中进行实验验证,结果证明,该调度算法明显减少了系统响应时间,提高了系统效率。
Aiming at the characteristics of node operating system and its demands for real-time performance,security and concurrency,this paper proposes a new kernel schedule algorithm for real-time system.By combining task priority dispatching with time slot cycling,it boosts the response speed of the processor,and improves the real-time characteristics of the system.The strategy is implemented on μCOS-Ⅱ,and the modified kernel is applied to the wireless acquisition system,whose result proves that the algorithm reduces response time of the system and improves its efficiency.
