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.
