Design of CAN Bus Data Processing System

Data processing is one of the most important sectors in CAN bus system. The paper design a universal CAN Bus data processing system. Describing block diagram, building processing method library with flexible way, it also design Data Processing procedure. Using ID code and ID mask code, CAN frame reconstruction is realized, then the parameter in the frame can be processed according to the corresponding parameter table. Loading processing method library into memory firstly improve data processing speed. At last, formula analysis and calculation methods are introduced, which have extensive value for data processing.
