[Software Engineering] GeneratingFPGA-AcceleratedDFTLibraries DL : 0: 关于DFT的文章，应用FPGA实现傅立叶变换。-Abstract—We present a domain-specific approach to generate high-performance hardware-software partitioned implementations of the discrete Fourier transform (DFT). The partitioning strategy is a heuristic based on the DFT’s divide-and-conquer algorithmic structure and fine tuned by the feedback-driven exploration of candidate designs. We have integrated this approach in the Spiral linear-transform code-generation framework to support push-button automatic implementation. We present evaluations of hardware-software DFT implementations running on the embedded PowerPC processor and the reconfigurable fabric of the Xilinx Virtex-II Pro FPGA. In our experiments, the 1D and 2D DFT’s FPGA-accelerated libraries exhibit between 2 and 7.5 times higher performance (operations per second) and up to 2.5 times better energy efficiency (operations per Joule) than the software-only version.

[Crack Hack] 06168353 DL : 0: The Fast Fourier Transform (FFT) is one of the rudimentary operations in field of digital signal and image processing. Some of the very vital applications of the fast fourier transform include Signal analysis, Sound filtering, Data compression, Partial differential equations, Multiplication of large integers, Image filtering etc.Fast Fourier transform (FFT) is an efficient implementation of the discrete Fourier transform (DFT). This paper concentrates on the development of the Fast Fourier Transform (FFT), based on Decimation-In- Time (DIT) domain, Radix-2 algorithm, this paper uses VHDL as a design entity, and their Synthesis by Xilinx Synthesis Tool on Vertex kit has been done. The input of Fast Fourier transform has been given by a PS2 KEYBOARD using a testbench and output has been displayed using the waveforms on the Xilinx Design Suite 12.1.The synthesis results show that the computation for calculating the 32-point Fast Fourier transform is efficient in terms of speed.
