首发时间:2010-08-25
摘要:本文提出了一种计算卷积的无乘法快速方法。该方法首先将卷积转换为一阶矩的形式,然后引入矩的快速算法来计算该一阶矩,从而实现了任意长度卷积的高效快速运算。根据该方法,文中设计了一种简单的脉动阵列来实现卷积运算,该阵列结构简单、无需乘法器和存储器的,有利于采用大规模集成电路实现。

Novel Convolutions using First-order Moments
Abstract:In this paper a novel convolution without multiplications has been presented via transforming it into the computation of the first-order moment. Then the method proposed for computing moments has been adapted to implement the arbitrary-length convolution efficiently. A very simple and scalable systolic array without multipliers and ROMs has also been designed to perform the convolution, which may result in the efficient VLSI implementation easily.
Keywords: Information processing technology Convolution First-order moment Systolic array
