TI's OMAP3530 for Digital Crossover?

[lnielsen]

Has anyone tried to use the TI's OMAP3530 as a digital crossover? There are currently two modules readily available; Beagleboard and Gumstix's Overo Fire.

The OMAP3530 has a TMS320C64x+ DSP core and five I2S interfaces. I know Russ White is using it with the Buffalo DAC, I would like to drive up to two 8-channel ESS Sabre DACs and a 2-channel ESS Sabre ADC. The device has two video interfaces, one could be used for a TV OSD and the other could drive a small LCD for the front panel. I would think this is a much better platform than a PC for DXO if it has enough power...

I am building my first pair of Linkwitz speakers using his analog active crossover and I would really like to play with digital but I know that I have a lot to learn before I can do this. If I build a complete HT setup I can replace at least seven analog active crossovers with one digital system.

Any thoughts?

Looks like huge overkill if all you'd like to do are a few audio XO filters. Why call up all that video processing grunt to get a digital XO? Do you really need two CPUs to do that? Agreed that many parts are short on the I2S interfaces - is this the only one which can manage over 4 channel output?
Implementing Linkwitz's analog XO in digital is no mean feat - I wish you luck!
