Rockbox Player - Project to design and build a Free/Open hardware audio player
Llorean:
Lossless codecs tend to take less power than Lossy codecs (with the exception of Monkey's Audio).
How fast, exactly, is this CPU?
saratoga:
ARM9 CPUs start at "faster then 1 core of a V1 Sansa" and get faster from there. Still saying "ARM9" doesn't tell us much, since theres a lot of very different processors sold under the ARM9 brand, with the common factor being that they were all before ARM10 and faster then ARM7.

It will be a LPC3130.
And the LCD($35) will have medium/good quality because the hardware is being tunning to be cheap - but the LCD will be for sure much better than that used on last prototype.
There will be other versions of base board of hardware that will have more RAM, for running Linux.
Bagder:
A quick check seems to indicate the primary CPU core related diffs are:
* they use the exact same ARM core (ARM926EJ-S)
* the LPC is clocked at 180MHz while the Atmel one is 190MHz
* the LPC one has 16KB data + 16KB instruction caches, while the Atmel one has 8+8

But this LPC3130 don't have DSP instructions has the AT91SAM9260 have. I think that DSP instructions could be good for audio processing.
