introspec	d5d788946e	Added an option for unrolling long match copying ... Usually useless and costing +57 bytes, this option can bring dramatic performance improvements on very compressible data dominated by long matches	2019-10-22 20:11:46 +01:00
introspec	495a12216f	-1 byte ... Very slightly faster too	2019-10-11 00:23:43 +01:00
introspec	566e3a94e8	+0.2% speed ... also, added an option to unroll LDIR for longer matches (which adds 38 bytes, but can be significantly faster for files with many long matches)	2019-10-10 22:50:23 +01:00

mobygamer	c38b582e73	Time-efficient LZSA2 decompressor ... This commit provides a time-effecient LZSA2 decompressor for the 8088 (and higher) CPU. Decompression speed is roughly 50% faster than ZX7 on the same hardware.	2019-07-13 22:35:28 -05:00

mobygamer	f123a6d9df	Submit 8086-optimized decompressor using jump tables ... Because the 8086's BIU is more efficient and can read a word in a single operation, we can skew LZSA1 decompression faster on 8086 by using a jump table to eliminate 2 comparions.	2019-07-11 17:22:29 -05:00
