摘　　要：数据缓冲是软件领域的常用开发技术,在多任务实时操作系统中,数据缓冲及相应的操作系统任务设计影响到整个系统的性能及稳定性。本文提出"高优先级-低复杂度"的操作系统任务设计原则,尽可能地将高优先级任务中的复杂工作量拆分到低优先级的任务当中,借助数据缓冲来完成工作的传递,由此带来系统性能的提升,在实际产品中取得了良好效果。Data buffer is a common technology in software development,in a multi task real-time operating system,data buffer and the corresponding operating system task design affects the performance and stability of the whole system.This paper put forward the“high priority-low complexity”principles of operating system task design,that is,split the work which is done in the high priority task,and put as much as the none real-time part into the lower priority tasks,while the work is transferred by buffer between tasks.This wil improve the performance of system,and be already achieved good results in actual products.
