Abstract

Residue Number System based signal processing is an efficient alternative to the conventional methods due to its small data size and parallel arithmetic operations. This paper presents the designs of the RNS to binary reverse converter, which is a critical component in a RNS based system. Different RNS modulo adders required to implement the reverse converter for the {2k-1, 2k, 2k+1} moduli set are evaluated. Their performances are then compared against each other. FPGA synthesis results are also presented to demonstrate the performance efficiency of the different designs.
基于RNS的数字信号处理系统的高效反向变换器设计
基于残数系统的信号处理具有数据量小、运算并行等优点,是传统信号处理方法的有效替代。本文介绍了基于RNS系统的关键部件——RNS -二进制反向变换器的设计。计算了实现{2k- 1,2k, 2k+1}模集的反向转换所需的不同RNS模加法器。然后将他们的表现相互比较。最后给出了FPGA综合结果,以验证不同设计的性能效率。
