Abstract: 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.
