基于嵌入式 LINUX系统的实时进程调度算法的研究
ON REAL-TIME PROCESS SCHEDULING ALGORITHM BASED ON EMBEDDED LINUX SYSTEM
摘要
Abstract
RTOS ( real-time operating system) is the core software in embedded computer.For applying and developing embedded operat-ing system, Linux system has distinct advantages, so it is widely used in research field of universities and enterprises.Nowadays the embed-ded technology develops rapidly, among which the requirement of real-time performance and reliability of RTOS calls for high quality.The main subject studied in this paper is the embedded Linux system.Its performance in terms of real-time performance and reliability has been good, but the traditional strategies all have some redundancy, so we study the optimisation of process scheduling algorithm for soft real-time system, and design a new optimisation algorithm.Through examination we obtain 50 data operation results, and analyse their value completion rate and process completion rate.The optimised algorithm greatly improves the efficiency of Linux system.关键词
