这是一个fft的IP核，安装要求为quartus6.0以上。解压安装后可在quartus里例化使用，元件主要为cyclone和stratix,最大支持1024点的转换。

To increase simulation speed, ModelSim® can apply a variety of optimizations to your design. These include, but are not limited to, mergingprocesses, pulling constants out of loops, clock suppression, and signal collapsing. You control the level of optimization by specifying certain switches when you invoke the compiler.

基于FPGA分布式算法FIR滤波器verilog代码 （本人 小论文 代码，通过验证） ​ 本文提出一种新的FIR滤波器FPGA实现方法。讨论了分布式算法原理，并提出了基于分布式算法FIR滤波器的实现方法。通过改进型分布式算法结构减少硬件资源消耗，用流水线技术提高运算速度，采用分割查找表方法减小存储规模，并在Matlab和Modelsim仿真平台得到验证。​ 为了节省FPGA逻辑资源、提高系统速度，设计中引入了分布式算法实现有限脉冲响应滤波器(Finite Impulse Response, FIR)。由于FIR滤波器在实现上主要是完成乘累加MAC的功能，采用传统MAC算法设计FIR滤波器将消耗大量硬件资源。而采用分布式算法 (Distributed Arithmetic, DA)，将MAC运算转化为查找表(Look-Up-Table, LUT)输出，不仅能在硬件规模上得到改善，而且更易通过实现流水线设计来提高速度。因此本文采用分布式算法设计一个可配置的FIR滤波器，并以31阶的低通FIR滤波器为例说明分布式算法滤波器结构。( FPGA verilog )
