Description: Basically, this article describes one way to implement the 1D version of the FFT algorithm for an array of complex samples. The intention of this article is to show an efficient and fast FFT algorithm that can easily be modified according to the needs of the user. I ve studied the FFT algorithm when I was developing a software to make frequency analysis on a sample of captured sound.-Basically, this article describes one way to implement the 1D version of the FFT algorithm for an array of co mplex samples.

Description: 本实验的目的在于学习FFT 算法，及其在TMS320C54X 上的实现，并通过编程掌
握C54X 的存储器管理、辅助寄存器的使用、位倒序寻址方式等技巧，同时练习使用
CCS 的探针和图形工具。另外在BIOS 子目录下是一个使用DSP/BIOS 工具实现FFT
的程序。通过该程序，你可以使用DSP/BIOS 提供的分析工具评估FFT 代码执行情况。-The purpose of this study is to learn FFT algorithm and its application in the realization of TMS320C54X and through programming master C54x memory management, the use of auxiliary registers, bit reverse addressing mode, such as skills, practicing the use of CCS at the same time the probe and graphics tools . Also in the BIOS is a subdirectory using the DSP/BIOS tool to achieve the FFT procedure. Through the program, you can use the DSP/BIOS analysis tools provided to assess the implementation of FFT code. Platform: |
