Paper Abstract

Image compression is used to handle large volume of digitized image data in order to minimize the time and cost required to store and transfer the digitized data. Image compression is one of the key components in emerging applications such as digital still video cameras, multimedia, color printers, video fax machines, and desktop publishing. This paper will describe the Zoran 031 image compression chip set. The chip set is comprised of the ZR36020 Discrete Cosine Transform (DCT) Processor and the ZR36031 Image Compression Coder/Decoder that work together to perform image compression and expansion. The chip set employs an algorithm for high quality compression of continuous-tone color or monochrome images, similar to the algorithm specified in the Joint Photographic Expert Group standard. The 031 chip set is targeted at cost-sensitive business and consumer applications such as digital still video cameras, color printers, color fax machines, and scanners. The architecture and the coding/decoding algorithm of the chip set as well as the add-in image compression PC board in which it is utilized will be discussed.
