- Description
- -----------
-
- ZENO is a LZ78-Packer, that keeps a dictionary of byte sequences in memory
- and output a code up to the length of selected code size.
- Its typical for those packers, that the compression ratio is better with
- data files than with executables.
-
- The differences to Bryan Fords 'BLZW' are, that ZENO's unpacking speed is
- more less, but memory use is less and compression ratio is better with
- lower modes.
-
- It was not possible for me to test the library with the standard
- XPK benchmark system (xbench, A3000/25 w. SCRAM, AmigaVision executable),
- but the values in the table below should be good approaches.
