Hi,

One of Altera's megafunction partner has something which is of your interest.

Please visit following: http://www.slscorp.com/index.php. ( In that, look into "Image Acquisition using USB3.0 IP core" ).

Unfortunatelly i can't use USB 3.0, USB 2.0 is way more common around here. I'll try to cram the data using compression.

I've taken a turn away from UVC, since i only need to output the pixel values to the USB, i'm thinking about designing a USB bulk endpoint, but i don't know if the Cypress EZ-OTG on the DE2-115 can handle it. Could anyone point me to some reference design?

As for compression, opencores has a JPEG encoder that might suite my needs (http://opencores.org/project,mkjpeg) and i'll stick with it for now. I'll focus on building the USB application for now.
