Study On Embedded DSP Multi-Interface Processing System

Embedded technology is one of the most comprehensive appliance fields.The advancement of technology and agility, convenience, efficiency of electric products come from embedded technology. Research and extensive appliance already become one of the most important objects in the process of informationary,and get the attention of academic community. DSP technology brings a revolution in the field of digital signal processing. DSP appliance develops more and more abroad because DSP integrates with embedded technology.Along with the improvement of chip speed,every high speed digital signal processing technology becomes more and more convenient,and systemic real time quality comes to be ensure.Because of the characteristics of complex arithmetic and large data,people seek incessant aim of finer digital signal processing arithmetic and higher speed processors.Based on the principle of embedded DSP technology,this thesis brings forward a new design plan of embedded DSP general system and completes it. At the same time,the agility and function increase because of the application of FPGA.The appliance of high speed multilayer board technology assures the quality of circuit board.This data processing system can apply to other electronic system,and have no need of large adjustment.This thesis also introduces the appliance in project of embedded system,and the system gathes and processes video frequency image data so as to analyse and process image precisely.This establishes a firm basement for the further realization of our advanced data process technology.The main reserch contents are as follows:First,the actuality currently of digital signal processing is discussed in detail,the technology of embedded and DSP and arithmetic of image process are comprehensively studied,which provide theoretic bases for establishing experimental project used the methods of introduced justly.Secondly,whole hardware system include conforming function,selecting chips,designing circuit board,debuging circuit is completed,At the same time,this thesis completes the process of high speed signal.
