摘要
提出一种基于FPGA实现32点实序列FFT的设计方法,采用基二时间抽取算法以及并行迭代处理方案。选择Altera公司Cyclone IV系列芯片,并用Verilog HDL完成设计输入。最后通过Signal Tap与Matlab数据对比发现,该设计可以实现对高速A/D采样数据的实时、准确处理。
A design method of 32-point real sequence fast Fourier transform(FFT) based on field programma-ble gate array(FPGA) is presented. Base-2 DIT algorithm and parallel iterative processing scheme are adopted. Cy-clone IV series chip of Altera company is chosen and Verilog HDL input method is used to implement design input.It is found that the design can achieve high speed A/D sampling data processing accurately and in real time throughcontrast of signal tap and Matlab data.
