What is it with this mythical DSP thingy, and how would it help in this & other (emulator) circumstances given what the Wizard has said?.. is anybody any closer to discovering, deciphering, conjuring.. smashing it's atoms & re-assembling or whatever the flip has to be done in order to utilise it's magical stardust..?
DSP: Digital Signal Processor. A second CPU that is very good at signal in-signal out kind of code. It would make simple work of taking a video file, for example, and outputing raw video data which can be displayed to the screen. Or MP3 into raw audio data (though we're not struggling much with that) or really lots of things. Exophase has some ideas about other things done in an emulator which could be offloaded to give a bit of a boost as well, but whether any of these things will actually happen or not is a big question.
The only thing holding us back is a driver to interface with the DSP. It is available in the 2.6.37 kernel, but the Pandora only has 2.6.26. At some point in the next few months, .37 (or at least .32, to which the module can be backported) should become available, just have a bit more patience. Notaz is a brilliant kernel dev, but he's got real life as well.
