Though the General-purpose processor was flexible in calculation, it was lack of efficiency, and ASIC was more efficient but less in flexibility. As a resolution the reconfigurable technology provide a very valuable developing direction. Reconfigurable technology can be a new useful technology in real-time signal processing, biologic information processing, simulation of VLSI, etc. It is a focal technology of international academy and industrial field.DFT is a common tool that is widely used in image processing and digital signal analysis. But the large scale of computation prevents it from been used in real-time system.This dissertation introduces concepts and advantages of reconfigurable processing, on the bases of these:1. Discusses the reconfigurable technology and its application foreground.2. Use FFT as an example algorithm, analyze the structure of the algorithm to build the reconfigurable system and to implement the design .the pipeline thinking was used in the schema.3. Puts forward two schemes related to float multiplier, and compares them.The key to the FFT algorithm is the design of butterfly computation and that of the address logic. The whole schema is designed in the top-down design flow and described in the VHSIC hardware description language(VHDL), basing on these, we do our research on reconfigurable technology.The result indicates that the data processing ability of reconfigurable system improved greatly. The system has the reconfigurable ability to implement different algorithms easily. Compared with traditional calculation system, RC system has strong adaptive computing capacity and saves hardware resources as well.
