Abstract: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.
Keywords:SylixOS  SMP  large system  real-time performance  performance optimization strategy
