调度延迟 meaning in Chinese
despatch delay
dispatch delay
Examples
- Based on the above schemes , this paper proposes the design of embedded realtime linux os used in terabit router , which combines low - latency scheme with preemption scheme to solve the non - preemptive kernel and replace the single running queue with multiple running queues in order to reduce the delay of scheduling . finally , it puts the schemes into reality and tests the performance
在对上述方案分析的基础上，结合t比特路由器对嵌入式实时操作系统的特殊要求，提出了t比特路由器嵌入式实时linux操作系统设计方案? ?低延迟与抢占方案相结合解决内核的非抢占机制，并且以多可运行任务队列来代替原来的单可运行任务队列的方法降低调度延迟。 - One way , linux kernel can be modified directly to reduce the schedule latency and this is so - called soft real - time . the other way , the so called sub - kernel idea can be adopted , which adds an extra real - time kernel besides linux kernel . the real - time kernel is in charge of managing and scheduling all the real - time tasks and linux kernel is treated as a real - time kernel ’ s task with the lowest priority
一种是对标准linux内核进行直接修改,通过减小操作系统的调度延迟,优化linux的实时性能,达到软实时的标准;另一种是采用双内核方案,增加一个实时内核,所有有实时要求的任务都在这个实时内核上运行,标准linux内核作为这个实时内核优先级最低的一个进程,这种方式可以实现硬实时。
