In the talk a review of proposals concerning the use of optoelectronic interconnects for FPGAs is given. The perspectives and the benefits of using optics for dynamically optical interconnects as well as optically reconfiguration of architectures are critically compared to the possibility of electronic 3D chip stack technology. The author sees a chance for optics in the optically reconfiguration of context memories in smart optical sensors since in this application an optical interface is anyway available or rather necessary for the detection of images. This interface could also be used for a dynamic reconfiguration in combination with modern 3D chip mounting and assembly technologies to realise smart and very compact CMOS camera chip stacks for embedded systems.
