摘要

交叉相关信号的基本运算在许多信号处理应用中是可行的。在典型的模式匹配应用程序中，相互关联是可取的。本文提出了一种适用于CMOS集成的时域互关器的低功耗实现方法。数据和模板的比特流编码简化了乘法运算。本文报道了一种采用90纳米技术的CMOS实现的测量性能。

Power efficient cross-correlation using bitstreams

The fundamental operation of cross-correlating signals is viable in a number of signal processing applications. In typical pattern-matching applications, cross-correlation is desirable. In this paper we present a power efficient implementation of a time-domain cross-correlator suitable for integration in CMOS. Bitstream coding of both data and template simplify multiplication operations. Measured performance of a CMOS implementation in 90 nm technology is reported.
