The real-time performance is improved by establishing a real-time task queue and executing a task rotation priority scheduling algorithm. 通过建立实时任务队列和执行任务轮转优先权调度算法来改进实时性能;
A new concept about interrupt priority cyclic rotation is proposed in this paper. The hardware placement and programming method for the discrete data acquisition system which is satisfied with the principle of interrupt priority cyclic rotation are discussed in detail. 本文提出了中断优先权循环浮动的新概念,讨论了离散型数据采集系统满足中断优先权循环浮动原则的硬件配置与软件设计方法。
After the improvement, the operating system μ C/ OS-II can create the same priority task. Tasks with the same priority use the time piece rotation scheduling, and tasks with different priority still used priority-based preemptive scheduling. 改进之后的μC/OS-II操作系统可以创建相同优先级的任务,相同优先级任务采用时间片轮转的调度策略,不同优先级任务仍采用基于优先级的抢占式调度机制。
As the planting area of xinjiang cotton increased year by year, and rotation of crop was difficulties, replaced variety to be quick, blinded introduction of varieties, all make the cotton blight more serious. disease-resistant cultivar selection of cotton breeding has become a top priority. 随着新疆棉花种植面积的逐年增加,轮作倒茬困难,品种更换加快和盲目引种等,造成棉花枯萎病日益加重,选育抗病品种已成为棉花育种的首要任务。
