Abstract

A single-chip two-dimensional discrete cosine transform processor is presented. This chip meets the challenge of high throughput rate (13.5 MHz) and versatility (block size from 4*4 to 16*16, and direct and inverse DCT) with a die area as small as 40 mm/sup 2/. An efficient optimized architecture providing high computation power is described. The chip is found to exhibit excellent precision performances. A full-custom approach was chosen because of the required speed and economic reasons (implementation of a low-cost real-time video coder/decoder). The chip uses a 1.25- mu m CMOS technology and contains 114000 transistors on 5.4*7.5 mm/sup 2/.<>
