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

mobygamer	b0c9d61aab	8088-speed-optimized LZSA1 decompression ... This commit contributes LZSA1 raw block format decompression code, optimized for speed for the 8088 and higher processors. With appropriate compression options (-f1 -m5), decompression speed is comparable to LZ4.	2019-07-07 20:25:50 -05:00
