New LZW Data Compression Algorithm and Its FPGA Implementation
This paper presents a new LZW data compression algorithm that partitions conventional single large dictionary into a dictionary set that consists of several small address space dictionaries. As doing so the dictionary set not only has small lookup time but also can operate in parallel. Simulation results show that the proposed algorithm has better compression ratio for image data than conventio...
متن کاملFPGA Based Data Compression using Dictionary based LZW Algorithm
Field Programmable Gate Array (FPGA) technology has become a viable target for the implementation of algorithms in different compression methods applications. In a distributed environment, large data files remain a major bottleneck. Compression is an important component of the solutions available for creating file sizes of manageable and transmittable dimensions. When high-speed media or channe...
متن کاملDH-LZW: Lossless Data Hiding Method in LZW Compression
In compressed data, there is not enough room available for data hiding, consequently many data hiding methods try to modify original data before compression. One of well-known lossless compression methods is LZW. It has been widespread due to wide use of GIF format. In spite of its reputation on compression, however, few data hiding methods are directly applicable to LZW itself. This may be due...
متن کاملThe relative efficiency of data compression by LZW and LZSS
We explore the use of the LZW and LZSS data compression methods. These methods or some versions of them are very common in use of compressing different types of data. Even though on average LZSS gives better compression results, we determine the case in which the LZW perform best and when the compression efficiency gap between the LZW algorithm and its LZSS counterpart is the largest.
متن کاملLZW Data Compression on Large Scale and Extreme Distributed Systems
Results on the parallel complexity of Lempel-Ziv data compression suggest that the sliding window method is more suitable than the LZW technique on shared memory parallel machines. When instead we address the practical goal of designing distributed algorithms with low communication cost, sliding window compression does not seem to guarantee robustness if we scale up the system. The possibility ...
