[Mathimatics-Numerical algorithms] fft

Description: FFT算法的基本原理是把长序列的DFT逐次分解为较短序列的DFT。按照抽取方式的不同可分为DIT-FFT（按时间抽取）和DIF-FFT（按频率抽取）算法。按照蝶形运算的构成不同可分为基2、基4、基8以及任意因子（2n,n为大于1的整数），基2、基4算法较为常用。-FFT algorithm is the basic principle of DFT successive long sequence is broken down into shorter sequences of DFT. In accordance with the different extraction methods can be divided into the DIT-FFT (time taken) and the DIF-FFT (according to the frequency of extraction) algorithm. In accordance with the composition of different butterfly operations can be divided into base 2, base 4, base 8, as well as arbitrary factor (2n, n is an integer greater than 1), radix-2, Radix-4 algorithm is more commonly used.

[Program doc] latch

Description: Abstract—Power is becoming a precious resource in modern VLSI design, even more so than area. This paper proposes a novel architecture for modular, scalable &reusable hybrid constant co-efficient multiplier (KCM) circuit. Comparison is made between of kcm and multiplier. The implementation results show a significant improvement in performance in terms of area, power & timing. In This paper, we propose to design an 8-point FFT using kcm instead of complex multiplier and multiplier. Here our goal is to implement Radix-2 8-point FFT in hardware using hardware language (verilog) here time constraint is measured with the help of Xilinx FPGA (Field Programmable Gate Array).
