| 摘 要： | 利用RNS(余数数制系统)可以执行并行的数据处理以及实现快速无进位算法,在VLSI(超大规模集成电路)设计中表现出低功耗、占用面积小和时延少等优良特性.根据中国剩余定理,基于(2n-1)2n(2n+1)模组,利用Verilog语言设计了RNS到位数据流的数值转换接口电路.以使传统的多位数(Bit)的复杂运算转化为多个并行的较少位数的简单运算,从而降低单次运算的复杂度、时延和功耗.该转换电路面向"Σ-Δ"编码的数据流,不同于传统的二进制数据转换,可以方便地与基于DSD(Direct Stream Digital)的Delta-Sigma系统进行无缝连接.

| Abstract: | Because the parallel data processing and the fast carry-free algorithm can be used by using Residue Number System(RNS) in VLSI(very large scale integration) design,RNS(Residue Number System) shows the high performance,such as low power consumption,small area,and short delay,etc.According to Chinese Reminder Theorem,based on(2n-1)2n(2n+1) Moduli set,the bit stream to RNS converting interface circuit is designed using Verilog language.So as to the traditional complex operation can be instead of the simple ope... |
