Non - preemptive priority queuing discipline 非强占优先规则
Non - preemptive priority queueing models with changeover times and switching threshold 带有转换时间和阈值的非抢占优先权排队模型
Based on no - preemptive priority queuing network model , new infinitesimal perturbation analysis schemes were presented to estimate the dynamic time performance of dms based on common ojbect request broker architecture ( corba ) and dimensional measurement interface standard ( dmis ) 针对基于公共对象请求代理结构和尺寸测量接口规范的分布式测量系统,根据多用户非抢占优先排队网络静态性能模型,提出基于无穷小摄动分析的分布式测量系统动态性能评价算法。
There is a pretty strict limit of reliability , cost , volume and energy - consuming . real - time embedded control system is applied for firm real - time and responding circumstance . aiming at direct current servo electromotor , a set of servo experiment system is designed , exploitation flow and process of real - time embedded control system are advanced , some issues of them are paid much more attention , the satisfied effects are obtained in the real circumstance , these issues include : exploitation of embedded system , analysis of superiority of the exploitation , the exploitation of embedded linux operation system from kernel customizing and file system cutting out to system starting up is researched , some factors which effect the system ' s capability are analyzed , the settled real - time schemes of linux os and the arithmetic of preemptive priority scheduling and round - robin scheduling and latest and rapid arithmetic are researched 本文围绕着针对直流伺服电机设计一套伺服试验系统,对于嵌入式实时控制系统应用技术进行了比较全面的研究,提出了嵌入式实时控制系统的开发流程和步骤,并对其中的一些问题进行了专门研究,在实物实验中获得了比较好的效果,这些问题包括:嵌入式操作系统开发,分析了使用linux操作系统进行嵌入式操作系统软件开发的优越性,并且从内核定制、文件系统裁剪、系统启动等几个方面研究嵌入式linux操作系统的开发;实时性研究,分析了在操作系统中影响系统实时性能的因素,研究了linux操作系统的几种实时解决方案,并且研究了基于优先级的可抢占式与可选择的同优先级按时间片轮转相结合的调度算法以及最迟响应与最快处理的可抢占式调度算法。
