The major difference in this to OMAP 3 is that the OMAP 3 does have access to host side memory but the co-processor doesn't --- as it's a CSI-2 link. Additional CSI-2 receiver (and a driver for it) is required on the host side. This receiver likely is not dependent on the co-processor so the driver shouldn't be either. For example, using this co-processor should well be possible with the OMAP 3 ISP, in theory at least. What would be needed in this case is... support for multiple complex Media device drivers under a single Media device --- both drivers would be accessible through the same media device. The co-processor would mostly look like a sensor for the OMAP 3 ISP driver. Its internal topology would be more complex, though. Just a few ideas; what do you think of this? :-) >>> Unfortunately the data-sheet of the co-processor cannot be made >> public >>> as of yet. >> >> Can you publish a block diagram of the co-processor internals ? > > I will check internally to see if I can send a block-diagram > of the co-processor internals to you.
