摘要
通过分析FFT的Cooley-Tukey算法,导出相应的IFFT算法。采用Altera公司的Cyclone Ⅱ系列FPGA芯片中的FFT megacore IP核定制FFT功能,分别使用Quartus Ⅱ和VHDL开发工具验证实现。
Based on the analysis of the Cooley-Tukey algorithm,an IFFT algorithm is described. This paper presents an IP core named megacore to customize IFFT function by using the Cyclone Ⅱ FPGA chip from Altera.The algorithm is verified in the Quartus Ⅱ development tool and VHDL separately.
