[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.

[Other] VHDL_Core_for_1024_Point_Radix_4_FFT_Computation.

Description: This paper shows the development of a 1024-point radix-4 FFT VHDL core for applications in hardware signal processing, targeting low-cost FPGA technologies. The developed core is targeted into a Xilinx庐 Spartan鈩?3 XC3S200 FPGA with the inclusion of a VGA display interface and an external 16-bit data acquisition system for performance evaluation purposes. Several tests were performed in order to verify FFT core functionality, besides the time performance analysis highlights the core advantages over commercially available DSPs and Pentium-based PCs. The core is compared with similar third party IP cores targeting resourceful FPGA technologies. The novelty of this work is to provide a lowcost, resource efficient core for spectrum analysis applications.

[DSP program] ADSP-21062_Compl_FFT_rad-4

Description: 用ADSP21062实现快速FFT基4算法 压缩包内有源代码和说明-In general, a radix-4 FFT will run faster than radix-2 FFT but will take up more space and has more restrictions on the length of the FFT. Specifically, all radix-2 FFT routines will take data lengths that are any power of two (>= 32 points) while complex radix-4 routines will only take data lengths that are a power of four (>= 64).

[DSP program] Radix-4FFTforTMS320C6000

Description: 用TI DSP芯片TMS320C6000实现FFT算法 内含程序代码和说明 The radix-4 FFT-Fixed-point digital signal processors (DSPs) have limited dynamic range to deal with digital data. This application report proposes a scheme to test and scale the result output from each Fast Fourier Transform (FFT) stage in order to fix the accumulation overflow. The radix-4 FFT algorithm is selected since it provides fewer stages than radix-2 algorithm. Thus, the scaling operations are minimized. This application report is organized as follows:

[Embeded-SCM Develop] fft-arm

Description: 一个用于ARM的基4/基5定点FFT算法，原作者是JDB，后来我扩展过16和256点的计算并用在项目中了，感觉速度还不错。现在重写了基于Linux GCC4的测试程序，可供使用者评估参考。建议安装FFTW3用来精确评估测试结果，相关范例已经在代码中了。-Radix 4/5 FFT routines supporting 16/64/256 and 20/80 calculations. The source originally contributed by JDB, I had extended 16 and 256 candidates and used it in our project it has been verified as fast and stable. Now we add some test vectors running on Linux with GCC 4 for testers who want to use or just evaluate it. Installing FFTW3 is recommended for evaluating the code exactly.
