基于分布式算法的多项抽取滤波器设计
Design of polyphase decimation filter based on distributed algorithm
摘要
Abstract
The distributed algorithm and polyphase decomposition technology are widely used to implement the high⁃order FIR filter and reduce the occupancy of FPGA hardware resource. The principles of the distributed algorithm and polyphase de⁃composition technology are introduced in detail. In combination with the characteristics of FPGA,a new algorithm suitable for high⁃order FIR filter is proposed,which can solve the problem that the distributed algorithm is adopted to realize the oversize high⁃order FIR filter lookup table,and improve the utilization of hardware resource. The implementation principles based on the distributed algorithm and polyphase decomposition technology are deduced. The high efficiency of this algorithm was realized and verified by ISE. The relationship of variation of the filter performance with the width of the filter coefficient quantization bit is given.关键词
