Methods for Improving Microprocessor fir Digital Filter Sampling Rate
-
摘要: 本文叙述用分布计算与查表相结合的方法,提高微处理器FIR数字滤波器的采样速度. 文中提出了高阶型和对称型FIR数字滤波器的系数分段法和对称系数分离技术,用以降低对 存贮器容量的要求.Abstract: In this paper, the sampling rates of FIR digital filters are improved by distributed computaions combined with table lookup. Coefficient Partioning Algorithm and Symmetrical Coefficient Split Technique are suggested for saving memory cost.
