A NEW DATA STRUCTURE FOR CUMULATIVE FREQUENCY TABLES (VOL 24, PG 327, 1994)
收藏 引用
SOFTWARE-PRACTICE & EXPERIENCE 1994年 第7期24卷 677-677页
作者: FENWICK, PM Department of Computer Science University of Auckland Private Bag 92019 Auckland New Zealand
A new method (the ‘binary indexed tree’) is presented for maintaining the cumulative frequencies which are needed to support dynamic arithmetic data compression. It is based on a decomposition of t... 详细信息

DESIGN OF HIGH-SPEED AND COST-EFFECTIVE SELF-TESTING CHECKERS FOR LOW-COST arithmetic CODES
收藏 引用
IEEE TRANSACTIONS ON COMPUTERS 1990年 第3期39卷 360-374页
作者: PIESTRAK, SJ UNIV GEORGIA DEPT COMP SCI ATHENS GA 30602 USA
Methods for designing self-testing checkers (STCs) for arithmetic error-detecting codes are presented. First, general rules for the design of minimal-level STCs for any error-detecting code are given. The design is il... 详细信息

Efficient universal lossless data compression algorithms based on a greedy sequential grammar transform - Part one: Without context models
收藏 引用
IEEE TRANSACTIONS ON INFORMATION THEORY 2000年 第3期46卷 755-777页
作者: Yang, EH Kieffer, JC Univ Waterloo Dept Elect & Comp Engn Waterloo ON N2L 3G1 Canada Univ Minnesota Dept Elect & Comp Engn Minneapolis MN 55455 USA
A grammar transform is a transformation that converts any data sequence to be compressed into a grammar from which the original data sequence can be fully reconstructed. In a grammar-based code, a data sequence is fir... 详细信息

Efficient statistical modeling for the compression of tree structured intermediate code
收藏 引用
COMPUTER JOURNAL 2003年 第5期46卷 476-486页
作者: Rai, S Shankar, P Indian Inst Sci Dept Comp Sci & Automat Bangalore 560012 Karnataka India
We propose a scheme for the compression of tree structured intermediate code consisting of a sequence of trees specified by a regular tree grammar. The scheme is based on arithmetic coding, and the model that works in... 详细信息
