Operating Frequency Improvement On FPGA Implementation Of A Pipeline Large-FFT Processor - 2017 PROJECT TITLE :Operating Frequency Improvement On FPGA Implementation Of A Pipeline Large-FFT Processor - 2017ABSTRACT:In this paper, circuit complexity reduction in FPGA implementation of enormous N-point Radix-22 FFT with single-path delay feedback design is reported. Memory demand of the FFT in the FPGA consists of two components, the RAM knowledge storage of the feedback in every stage of the info flow and the twiddle factors ready as ROM for each advanced multiplication. Through address rearrangement, the ROM sizes for the twiddle factors are significantly reduced with the removal of redundancy. The reduction ratio is regarding 1/three(log4 N-1). As a result, the signal essential path is reduced and also the system clock frequency is increased. The proposed design is validated by the implementations of 1K and 4K Radix-twenty two FFTs in an Altera Cyclone IV FPGA, EP4CGX22, that is that the second lowest capability FPGA of the low price series. For the 1K- and 4K-purpose FFTs, the operating frequencies are 231.eleven MHz and 215.seventy five MHz, respectively, approaching 250 MHz which is that the speed limit of the I/O ports of the FPGA [one].
