Abstract
A decompression approach utilizing a single buffer to reduce working memory space decompression requirements. Loading a compressed data file into the "back end" of a buffer and progressively loading the resulting decompressed data into the "front end" of the buffer avoids allocating multiple buffers for the decompression process. Using a slop value to increase the size of the allocated buffer beyond the original uncompressed data size avoids inadvertently overwriting not yet uncompressed data still residing in the back end of the single buffer when storing just decompressed data in the front end of the single buffer.
