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

M ONTANA  S TANDARDS   FOR  A RTS Arts have intrinsic value. They cultivate the whole child, building many kinds of literacy while developing intuition, reasoning, creativity, imagination, and dexterity into diverse forms of expression and communi- cation. The Arts enable students to make decisions and seek multiple solutions. They improve perception, reflection, and creative thought. They advance higher order thinking skills of analysis, synthesis and evaluation. The Arts provide powerful tools for understanding human experiences and cultures—past, present and future. Arts education engages students in a creative process that helps them develop the self-motivation, discipline, cooperation and self-esteem necessary for success in life. The Arts consists of Dance, Music, Theatre and Visual Arts. The content and performance standards for the Arts describe what all Montana students should know and be able to do in the Arts. Although literary arts are generally considered a part of the Arts, standards for the literary arts are integrated through- out the Communication Arts. Content Standards indicate what all students should know, understand and be able to do in a specific content area. Benchmarks define our expectations for students’ knowledge, skills and abilities along a developmental continuum in each content area. That continuum is focused at three points—at the end of grade 4, the end of grade 8 and grade 12. Content Standard 1—Students create, perform/exhibit, and respond in the Arts. Content Standard 2—Students apply and describe the concepts, structures, and pro- cesses in the Arts. Content Standard 3—Students develop and refine arts skills and techniques to express ideas, pose and solve problems, and discover meaning. Content Standard 4—Students analyze characteristics and merits of their work and the work of others. Content Standard 5—Students understand the role of the Arts in society, diverse cultures, and historical periods. Content Standard 6—Students make connections among the Arts, other subject areas, life, and work. 10/00 -1-

Arts Content Standard 1 Students create, perform/exhibit, and respond in the Arts. Rationale Students understand and express themselves in depth through an art form by: •generating original art; •participating, re-creating, and exhibiting; and •reacting and placing value. As a result, they arrive at their own knowledge and beliefs for making personal and artistic decisions. Benchmarks Students will: End of Grade 4 1.identify their own ideas and images based on themes, symbols, events and personal experiences. 2.use a variety of materials and sources to experiment with an art form. 3.present their own work and works of others. 4.collaborate with others in the creative process. 5.describe how a variety of materials, techniques and processes cause differ- ent responses. 10/00 End of Grade 8Upon Graduation—End of Grade 12 1.create a work from their own ideas and1.conceive and create works of art. images based on themes, symbols, events and personal experiences. 2.select a variety of materials and sources2.demonstrate imagination and technical to demonstrate a specific art form.skill in a minimum of one art form using traditional and nontraditional resources. 3.prepare and/or revise works for presen-3.select or adapt the elements of a presen- tation.tational style. 4.collaborate with others to make artistic4.apply artistic discipline (e.g., concentra- choices.tion and focus) to complete a collabora- tive work. 5.describe and analyze artistic choices in5.articulate meaning by describing and their own work and works of others.analyzing artistic choices in their own work and works of others. -2-

Arts Content Standard 2 Students apply and describe the concepts, structures, and processes in the Arts. Rationale The ability to use and share knowledge is fundamental to human experience. The Arts: Dance, Music, Theatre, Visual Arts, provide many of the tools for students to successfully interact with their world.
