摘要
龙芯3A处理器具有高性能低功耗的优点,在高性能计算、个人桌面应用、工业控制、高性能嵌入式等领域都有广阔的应用前景.目前龙芯系列平台大都是基于Linux系统,但在工业控制、高性能嵌入式等领域,高实时性和高可靠性的VxWorks才是比较理想的选择.在分析了VxWorks移植的主要内容基础上,详细研究了龙芯3A的VxWorks移植方法.针对具体工业应用,设计了一种基于龙芯3A的工控平台,并实现了对该平台的VxWorks移植.经过在龙芯3A开发板上的验证是可行的.
Loongson3A processor has the advantages of high performance and low power consumption,which has broad prospects in high performance computing,personal desktop applications,industrial control,and high performance embedded fields.At present,Loongson series platform is mostly based on Linux.But in industrial control and high performance embedded fields,VxWorks is the ideal choice,which is high real time and high reliability.Based on the analysis of the key contents of VxWorks porting,this paper researched the VxWorks porting approach of Loongson3A.According to the specific industrial application,designed a kind of Loongson3A industrial control hardware platform,and implemented VxWorks porting on this platform.It is feasible by verified on Loongson3A development board.
