I'm well known to over-optimize for both size and speed. I have an old Pentium 3 800MHz single core that I can use to simulate an embedded device (well, a decently powered one), to verify that I'm not killing the single-core performance (I could add CPU capability detection to help with that). Also, I still need to find time to do all this research and development. -Brandon On 10/2/2012 3:06 AM, Adrian Chadd wrote: > .. please keep in mind that embedded platforms (a) don't necessarily > benefit from it, and (b) have a very small footprint.
