摘要

设计高性能、高精度、实时的数字信号处理(DSP)系统，特别是与小波信号处理相关的DSP系统，是一个具有挑战性的问题。本文报道了残数系统(RNS)在实现高端小波滤波器组中的创新应用。公开的系统使用在伽罗瓦字段上定义的增强索引转换来有效地支持不同的小波滤波器实例化，而不增加任何额外的成本或额外的查找表(LUT)。针对不同的定制IC技术，对现有的两个互补(2C)设计进行了详尽的比较。这些结构已被证明非常适合于现场可编程逻辑(FPL)同化以及CBIC(基于单元的集成电路)技术。

Index-based RNS DWT architectures for custom IC designs

The design of high-performance, high-precision, real-time digital signal processing (DSP) systems, such as those associated with wavelet signal processing, is a challenging problem. This paper reports on the innovative use of the residue number system (RNS) for implementing high-end wavelet filter banks. The disclosed system uses an enhanced index-transformation defined over Galois fields to efficiently support different wavelet filter instantiations without adding any extra cost or additional lookup tables (LUT). An exhaustive comparison against existing two's complement (2C) designs for different custom IC technologies was carried out. These structures have been demonstrated to be well suited for field programmable logic (FPL) assimilation as well as for CBIC (cell-based integrated circuit) technologies.
