摘要

利用低成本残差/商码(LCRQ)，提出了一种新的二维离散余弦变换(DCT)设计。该方法以LCRQ编码为基础，将二维离散余量变换分解为基于残差的模块和基于商的模块实现离散余量变换的计算。性能评估表明，基于lcrq的二维DCT实现可以将传统DCT的计算速度提高到76.4%，且硬件设计要求较低。

A novel 2-D DCT realization using low-cost residue/quotient technique

This paper proposes a novel two-dimension (2-D) discrete cosine transform (DCT) design by using the low-cost residue/quotient (LCRQ) codes. Based on the LCRQ codes, the proposed method divides the 2-D DCT into residue-based module and quotient-based module for realizing the DCT computations. Performance evaluation shows that the proposed LCRQ-based 2-D DCT realization can speed up the traditional DCT computation to 76.4% with less hardware design requirement.
