What is the DSP used for?
 

Since we know that the 1710 OMAP in the 770 is a 200mhz dual-core processor with a dedicated DSP half, I was wondering how much that DSP is used to speed up/enhance the device's performance.

I was watching the Ice Age trailer the other day and it seemed choppy to me. Is this something that the DSP should be able to render flawlessly?

So how much is the DSP core really being used?

If it is not yet fully implemented yet, what improvements can we expect as newer firmware moves more processing to the DSP (if it does)?

Video player and audio players use solely dsp. There is at the moment an ongoing discussion on the developers list on whther the processor would actually perform better in video decoding task than the dsp and whether some other dsp algorithm would be better for mpeg4 decoding than the current one used.

I don't think dsp is used in much else besides those stated above. Might be used for jpeg decoding as well.

anyone remember that bit in the Ring at the beginning where she opens the door and there are lots of flashing images from the TV ---- well at a low resolutioon and sound quality or like 48kbs - but i higher 25frames per second - it totally couldnt render any of it - and just froze on her scary face- was kinda funny though. anyways -after that the picture is really pixelated for about 30secs :confused:

Noise always throws codec and DSPs into a fit. If it was VBR then the bitrates went way up.

Same thing will happen if you ever en/decode a close up of crashing waves.

I should clarify that by 'noise' I mean high motion/color chaging in video with the best example being static, and in audio, also static/noise.
