This paper presents a reconfigurable high speed real-time info processing system based on AD14060 using FPGA and multi-DSPs. It analyses the system structure and working principle of main processing board, expand board of multi-DSPs and display module in detail. The system combines merit between FPGA and DSP, such as, rapidity,agility and currency. It is important for the system that it is easy to modularize, expand and then it can improve the parallel efficiency of algorithm. Experimentation shows that exploitive period of the system is short, maintenance convenient. Thus it is fit for real-time signal processing and can get satisfactory effect of image processing.
