Jens Arnold	4a6190dd13	Hopefully fix FS #8840 for iAudio M3, M5 and X5. Reduce greyscale update frequency on M3 in order to reduce CPU load (was >50% before, but this fix would have made it even worse). ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17621 a1c6a512-1295-4272-9138-f99709370657	2008-05-24 08:53:12 +00:00

Jens Arnold	40919d7db2	iAudio M3: Optimised LCD driver, with more/better assembly code. Speedup is ~80% when boosted, ~15% when unboosted. Also implemented grey phase blitting. * Adapted the greyscale library, and the plugins using it. * Fixed a bug in greyscale scroll down for vertically packed pixels. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16809 a1c6a512-1295-4272-9138-f99709370657	2008-03-25 23:21:36 +00:00
