Hi
Microsemi SOC Division (Actel) have a solution produced for them by Attodyne which rins in their Igloo family, but is suitable for all Actels flash-based devices. The demo board supports a single camera, but the IP is configurable and, with Microsemi or Attodyne help, you should be able to achieve your design.
The IP is free, but you will need to sign and IP NDA with Microsemi before it can be released. Talk to your local Microsemi or Avnet reprsentative to get more detail and support.
