The past years have seen a rapid development in the area of image compression techniques, mainly due to need fast and efficient techniques for storage transmission data among individuals. Compression is process representing compact form rather than its original or incompact form. In this paper, integer implementation Arithmetic Coding (AC) Discreet Cosine Transform (DCT) were applied colored im...

This document explains background material for the ling of two patents, EEcient interval width update in arithmetic coding, and Design of fast circuits for code point update in arithmetic coding. The aim is to give the reader the necessary technical foundation to understand the ideas in the patents, and appreciate their signiicance.

We present a cost optimal parallel algorithm for the computation of arithmetic coding. We solve the problem in O(log n) time using n/log n processors on EREW PRAM. This leads to O(n) total cost.

This paper extends the result of earlier work on the application of arithmetic codes to the constrained channel problem. We specifically present a general length-based $xed rate implementation technique which performs the arithmetic coding recursions during each channel time unit. This technique is superior to an earlier unpublished code for general constrained channels. The approach permits th...
