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 )
