Based on the practical application of information processing system on the real-time embedded operating system VxWorks, as an example of parsing and processing GPS messages with multithread serial port, the technology of the BSP configuration under VxWorks, and how to set the serial port and multithread environment are studied in this paper. Then, the key technologies of GPGGA messages are collected, resolved and processed through serial port. Finally the overall architecture of the information processing system, the design of multithread serial port and GPGGA parsing algorithms are proposed.
