Realization of LZW Compression Algorithm in Multi-channel High Speed Data Acquisition System

In this paper,multi-channel high-speed data acquisition system,with its features of multiple channels,high-speed sampling and a large of quantity of data,LZW compression algorithm is described in detail in the application of the system,that is,the concrete implementation methods of construction,removal and reconstruction of a dictionary as well as the construction of compression frame.After a C-point simulation and practical application of data acquisition system,the results show that the algorithm has good compression rate and high compression speed.
