Only if you would optimize the existing codecs to use said DSP instructions. I would expect that to be quite complicated and not for the faint of hearted in the audience. And there's nothing like that done for existing ARM targets.

Ok. The most important now is to have a cheap base hardware (but including good LCD, audio).
On next iterations we can rethink about this subjects.
The boards (without plastic case) cannot cost significantly more than $100. Let's see if we can get this objective. With netbooks with ARM for $150 or less on next months and economic problems, it's difficult to justify buying this hardware.
kugel.:
The LPC3130 has only one storage interface. Didn't you want to have internal and external storage? Or is it still possible with only 1 interface?

That was never the case. And there's no two separate things either really, unless you count the bootloader and the Rockbox core as different but they're built with the same compiler. This new SoC will of course use the exact same compiler as before.

The early schematics are here. You need to install KiCAD for see them.
Sorry, I need to look careful to schematics - I am not the one that is designing it nor choosing the components. I think we can choose also the LPC3131.
I think system will use NAND flash for boot but can also boot from SD Card (although I don't know how we will do with the royalties for using SD bus).
