I'm helping Thierry Tremblay test his port of PocketHAL for the PalmOS. It's been pretty interesting trading ideas back and forth because Theirry keeps his source code pretty close to himself, but he drops hints here and there as to how he has optimized a lot of his ARM blitting routines. Thierry's Pocket Frog has been around for a while, and as such, his ARM assembly has been refined to the point that it's blazingly fast. However, the architecture of his original code base and the limitations imposed by the PalmOS have made for some interesting discussions about implementation. I'm excited to see how it all turns out. As of this posting, it still has a long way to go.
