摘要
数值缩放(scaling)和奇偶检测等的高效VLSI实现已经成为剩余数系统(RNS)研究的瓶颈问题。该文基于4模集合{2n,22n+1,2n+1,2n-1},在新中国余数定理的基础上,提出了该模集合优化的2n比例变换优化算法,并基于VLSI实现其硬件结构。分析结果表明,该2n比例变换的VLSI实现具有更好的面积和功耗特性。
Scaling and parity check in RNS has always been conceived as a performance bottleneck similar to the residue system.In this paper, a simple and fast 2nscaling scheme for the four- moduli set { 2n, 22n+1, 2n+1, 2n-1 } RNS is proposed baesd on the new Chinese remainder theorem. The analysis result shows that the proposed scaler has higher area and power consumption perfor-mances compared with the cascaded scaling scheme.
