Based On Dsp + Fpga Can Bus Data Communication System

Controller Area Network is one of the Area Network which applied mostpopular in worldwide. It's a muti-master serial communication Bus. It hashigh rate in the industry control communication area, high performance inEMI, and has capability to check all the mistakes. CAN Area Network has beenalready used in the lots of industry control Area with it's flexible andreliable.Controller Area Network communication system base on FPGA and DSP isdedicate to build CAN muti-node communication with high speed andreliability. Through communication between all nodes and node processorprocess internal date to realize system collaboration.This thesis is to realize CAN real time communication between infraredtarget detect system and control system, image-process system. It uses theFPGA and DSP to make core processor unit. This system realize the muti nodesreliable communication out of processor and SPI serial communication in theprocessor unit through DSP programming FPGA model designing. Thus this systemcomplete the date applied and process in the FPGA.
