lol. IVA stands for Imaging and Video Accelerator. It's mentioned on the OMAP2420 page and the pdf from there says it can do some nifty things (http://focus.ti.com/pdfs/wtbu/TI_omap2420.pdf).

The TMS320* stuff is the name of a Ti DSP, we also have a TM320C55x DSP on the OMAP2420 and 1710 (is that the right one for the 770). So it looks like the OMAP3 has twin DSPs, one designed to do audio stuff (like on our OMAP2420) and one to do video stuff built into the IVA2. the question is then is our IVA actually a DSP? And how on Earth can we use it?

There is some mention of enabling the IVA in the DSP Gateway code (it's been changed so that more than one DSP/Co-processor (as I don't know if it's a DSP) can be accessed, but my understand is that there's no kernel for the IVA.

HTH, but it may just confuse even more!
