- Description:
-
- The LZH package consists of two modules for compression and decompression of
- files. They are similar in style to John Kortink's LZW modules but provide
- significantly greater compression with similarly low overheads (only 32k on
- decompression). The compression techniques used are a Finite window technique
- with secondary dynamic huffman compression similar to gzip/zip/pkzip (but not
- the same). The modules are written in 100% lovingly handcrafted ARM code and
- are very fast (relatively) on compress and decompress.
-
- There are currently two modules supplied here, LZH and LZHD. The LZH module
- allows both compression/decompression of files, and the LZHD module allows
- just decompression of files. Note: The LZHD module claims all workspace it
- needs when it is loaded, so there is no need to keep RMA free for it. This
- is for ease of use in memory tight situations.
