I just started playing with the CP again this weekend, reading the hardware reference manuals, setting up hardware timers, doing some rendering, the usual fun stuff :)

Now I'm wondering if anyone have made any use of the Classpad DMA unit.
Specifically, what kind of transfer sizes you need to see benefits, any potential pitfalls regards to cache coherency and such, and if it even works for memory to memory transfers (from what I gather in the docs, this should be possible).

Hello BiTwhise,

Are you sure that ClassPad uses a DMA controller to transfer data ?

Please inform me where can I find the documents you mentioned, that describe the hardware of the ClassPad.
