While I'm around, I've been looking for a good compressor for an embedded scenario, where compression time and memory is near-irrelevant (it's done offline), but streaming decompression time and memory use (both in code and scratch memory) is primordial. By memory use, I'm talking a system with single-digit megabyte RAM, and decompressor scratch memory usage in the dozens of kilobytes.
Right now, we're using LZSS because the decompressor code is tiny (hundreds of bytes), and scratch memory is in the single-digit kilobytes.
Any suggestions? All benchmarks I can find online are focused on desktop usage (where comp/decomp memory use is either not mentioned or in the megabyte range) or web streaming usage (where total comp+decomp time is important. I don't care (within reason) about comp time)
