Fast Arithmetic Coding (FastAC) Implementations Amir Said 1 Introduction This document describes our fast implementations of arithmetic coding, which achieve opti- mal compression and higher throughput by better exploiting the great numerical capabilities of the current processors. References [1, 2] contain descriptions of the particularities of the coding methods used, and reference [3] presents the experiments and speed measurements used for optimizing our code. Objectives During the development of our program we had the following objectives: 1.

• unsigned max code bytes
• unsigned char
• adaptive data model
• plot segment
• current color
• compression
• version
• function
• bit
• data
