Abstract


Digital signal processing is one of the information sciences in recent decades the most rapidly developing discipline . Currently, digital signal processing has been widely used in areas such as communications, radar , sonar , voice and image processing . Discrete Fourier transform (DFT) plays an important role as a basic transformation in digital signal processing , However , due to the amount of computation of the discrete Fourier transform (DFT) is too large , the proposed after a period of time and not in the actual project has been applied until the Fast Fourier Transform (FFT) algorithm proposed reduced when N is large the DFT computational complexity , which makes the DFT specific application in the actual project , which also further promote the development of digital signal processing technology . FFT algorithm appears to now have 40 years of history , algorithm theory has mature , specific methods constantly updated . The real - time processing of the FFT of the data stream for high - speed , large-capacity through data parallel processing or multi - stage pipeline structure to achieve. This paper analyzes the discrete Fourier transform and its fast calculation method FFT . The four common practice used to FFT processor hardware circuit structure is introduced , and analyze their respective characteristics . Realized according to the characteristics of the algorithm and hardware structure Difficult , select a hardware configuration method yl -2 FFT algorithm and pipelining work extracted by Time to design the FFT processor , this structure has a certain extent improve the FFT processor processing speed , and design using the IEEE single-precision floating - point data in the form normalized calculated to improve the accuracy of the calculation . Selection XILINX Virtex II series FPGA chip XC2V8000, ISE 7.1 design platform using Verilog HDL hardware description language design pipeline work FFT processor to calculate the length of the data for 1024 point . MATLAB computing software last used test simulation of FFT processor design , the theoretical value calculated in MATLAB FFT and FFT processor computing results were compared with the calculation error . Simulation results show that the calculated results to the requirements of a single-precision floating - point number , computing speed to meet the requirements of real-time signal processing .
