FIR verilog
应用背景
FIR(Finite Impulse Response，有限冲击响应)数字滤波器具有稳定性高、可以实现线性相位等优点，广泛被应用于信号检测与处理等领域[1,2]。由于FPGA(Field Programmable Gate Array，现场可编程门阵列)基于查找表的结构和全硬件并行执行的特性，如何用FPGA 来实现高速FIR 数字滤波器成了近年来数字信号处理领域研究的热点。目前，全球两大PLD 器件供应商都提供了加速FPGA 开发的IP(IntelligentProperty，知识产权)核[3]。本文在Altera 公司的FIR 数字滤波器IP 核的基础上，设计了基于分布式算法的FIR数字低通滤波器。
