Paper Abstract

The Discrete Cosine Transform (DCT) is considered to be the most effective transform coding technique for image and video compression. In this paper, a new implementation of an experimental prototype multi-function DCT/IDCT (Inverse DCT) chip is reported. The chip is based on a distributed arithmetic architecture. The main features of the chip include: 1) The DCT and the IDCT are integrated in the same chip, 2) the chip achieves high accuracy, exceeding the stringent requirements of a proposed CCITF standard, 3) it achieves a high operating speed of 27 MHz, and is thus applicable to a wide-range of real-time image and video applications, 4) the internal clock frequency is the same as the pixel rate, and 5) with an on-chip zigzag scan converter and an adder/subtractor, it is multifunctional and useful in a DPCM configuration. The chip is implemented with standard cells and contains about 156k transistors.
