Sliding Window Update Using Suffix Arrays

Artur J. Ferreira, Arlindo L. Oliveira, Mário A. T. Figueiredo

Abstract: The sliding window (SW) Lempel-Ziv (LZ) 77 algorithms are widely used for universal lossless data compression. The LZ77 encoding component performs repeated substring search. Data structures, such as hash tables and trees have been used for fast search, at the expense of memory usage. Recently, suffix arrays (SA) have been used for dictionary representation and LZ77 decomposition, using less memory than those data structures.
