SylixOS大型实时操作系统实时性分析

Real-time Performance Analysis of SylixOS Large Real-time Operating System

SylixOS是一款支持多架构的64位国产原创操作系统,支持SMP与AMP多核架构,系统内核功能丰富,系统提供丰富的文件系统支持、完善的网络协议栈支持与多种图形显示引擎支持。SylixOS作为一款大型RTOS,在实时性方面做了很多有益的设计,但是,系统的实时性与使用过程中的众多因素相关,本文对影响实时性的因素进行分析,并给出优化方法,最后给出SylixOS和VxWorks的测试对比。

SylixOS is a 64 bit domestic original operating system supporting multi architecture,supporting SMP and AMP multi-core architecture,with rich kernel functions.The system provides rich file system support,perfect network protocol stack support and a variety of graphic display engine support.SylixOS is a large-scale RTOS,which has done a lot of useful design in real-time,but the real-time performance of the system and the difficulties in the process of use are limited.This paper analyzes the factors that affect the real-time performance,and gives the optimization method,and then gives the test comparison between SylixOS and VxWorks.
