Design Of The Image Processing System On DSP

Image processing system has been widely used in many very important situations in modern society. The image processing system we used nowadays are mainly based on image processing card ,which has to turn to the high computing speed and large memory capacity of computer to accomplish the work related to image processing. This way is very simple ,but then the shortcomings such as bulky ,expensive and unstable to the designed system are also coming along. To avoid these disadvantages, we put forward a complete "embedded" image processing system in the thesis. This image processing system is based on DSP, which can accomplish some work such as image sampling , converting , processing and displaying without computer. This is a complete "embedded" system , which is handy, cheap and stable, especially suitable for industry using.The core device of this "embedded" image processing system is a high performance fixed-point digital signal processor (DSP) produced by TI corporation-TMS320C6204,which has so powerful hard structure and variable tough function instructions ,along with its super computing speed of 1600MIPS that it can realize the complete "embedded". According to the features of image processing, we have applied some peripherals such as A/D and D/A converter, First In First Out RAM, Synchronous Dynamic RAM,FLASH ROM and so on in this system in order to achieve our goals of image sampling .processing and displaying, which can isolate this image processing system from others ,and realize the completely "embedded".
