[Windows Develop] How to implement the FFT algorithm

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. 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 wa s developing a software to make frequency Analytics sis on a sample of captured sound.

[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.
