简介 快速傅里叶变换(Fast Fourier Transform)最为一种高效的算法,被广泛的用于信号处理与数据分析等领域.对于设计工程师来讲,自己动手采样可编程语言来实现一个FFT/IFFT模块,不知要花费多少心血.所幸的是Altera和Xilinx两大巨头都提供了自己FFT核,本文将详细讲解如何使用Altera的FFT核. Altera FFT核 FFT IP core的总体架构分析:FFT分为fixed transform size architectture 和 variable st
The FFT core provides four architecture options to offer a trade-off权衡取舍 between core size andtransform time.• Pipelined Streaming I/O – Allows continuous data processing.• Radix-4 Burst I/O – Loads and processes data separately, using an iterative a
LPC4350 SGPIO Experimentation The NXP LPC43xx microcontrollers have an interesting, programmable serial peripheral called the SGPIO (Serial GPIO). It consists of a slew of counters and shift registers that can be configured to serialize and deseriali
