Lossless data compression in real time

This paper describes the research effort currently in progress to develop lossless data compression algorithms for seismic, speech, and image data sets. For many applications, such as transmitting and archiving research data bases, using lossy compression algorithms is not advisable. In situations where critical data (e.g. research instrumentation) is to be transmitted or archived, a real time lossless data compression algorithm is desirable. It presents a version of the algorithm using a recursive least squares a priori adaptive lattice structure followed by an arithmetic coding stage. The real time effectiveness of this algorithm is being verified by coding the technique to run on a TMS320C3x card custom developed for our applications.<<ETX>>
