The scheduling technique is the heart of any real-time system which is responsible for making decision about execution order of tasks in the system so any kind of overlapping can be avoided. In this papers, the classification of several scheduling techniques have been done based on different ...
刘教授是计算机实时系统领域的开山祖师,他在1973年发表的论文Scheduling Algorithms for Multiprogramming in a Hard-Real-Time Environment可以称得上开天辟地,他在这篇论文中提出了著名的Liu&Layland上限,这一理论也成为了计算机实时系统设计的基本准则。许多实时系统中的问题都来源于此,例如多核处理器出现之后,实时系统从...
Algorithms and complexity concerning the preemptive scheduling of periodic, real-time tasks on one processor We investigate the preemptive scheduling of periodic, real-time task systems on one processor. First, we show that when all parameters to the system are in... SK Baruah,RR Howell,LE ...
Real-time scheduling constraints are necessary to manage data acquisition or process control hardware. The real-time environment requires that a process be able to react to external events in a bounded amount of time. Such constraints can exceed the capabilities of a kernel that is designed to pr...
This paper presents several algorithms for real-time scheduling that have been developed following an approach known as Imprecise Computation. This technique prevents timing faults (i.e., results not produced in time) by offering an approximate result of an acceptable quality whenever the exact result...
An overview of scheduling algorithms in wireless multimedia networks Scheduling algorithms are important components in the provision of guaranteed quality of service parameters such as delay, delay jitter, packet loss rate, ... H Fattah,C Leung - 《IEEE Wireless Communications》 被引量: 708发表: ...
Real-time transactions will restart or abort possibly for competing limited system resources in low bandwidth environ-ments and the unpredictable system workloads in mobile environments.Conventional scheduling algorithms of real-time transactions cannot adapt this situation,so a novel scheduling algorithm of...
In this way, productivity, security and costs in the development cycle can be improved. The schedulers can be easily changed, providing a framework to test new scheduling solutions. 关键词: operating systems real-time scheduling algorithms time-sharing systems 会议时间: May–June 1995 被引量:...
