Abstract

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.
