摘要

A low power discrete cosine transform (DCT) architecture is presented. It is implemented through Loffler DCT based on the coordinate rotation digital computer (Cordic) algorithm and the canonical sign-digital (CSD) multiplier-less architecture. The synthesis results show that the proposed 8-point one-dimensional DCT architecture consumes lower power and smaller area.
