摘要
介绍基于查找表结构的分布式算法的基本原理,提出M位并行分布式算法的实现方法。以2位并行分布式算法结构的FIR滤波器设计为例,在Altera Cyclone系列芯片上实现32阶12位FIR滤波器,并对其性能和资源占用进行分析。
The distributed arithmetic is introduced in this paper and an efficient architecture for the FIR filter basedon FPGA is proposed that employs the M-bit parallel distributed arithmetic(M-bit PDA).Altera Cyclone is used as a target device.A 32-tap FIR filter is designed using the 2-bit PDA structure.Its performance and hardware consumption are analyzed in this paper.
