Abstract
Several kinds of algorithms applied to high-order FIR filter are introduced,among which the DA algorithm is em-phatically introduced. The algorithm mainly based on the form of LUT reduced the resource consumption of multiplier radically and improved the real-time performance of the system. On this basis,several kinds of improved algorithms are presented in this paper. They are the improved DA algorithms,respectively based on LUT decomposition,OBC coding and two-way selector. They improved the speed of signal processing and reduced the system complexity. The comprehensive analysis,comparison and simulation for the improved DA algorithms applied to FIR filter are carried out. The results of simulation are correct and meet the design requirements.关键词
