  1. Hello! I have been investigating how multiple clock domains work and how you can send data ASAP from a camera module to a SDRAM (taking a pic). I am currently using a Nexys-Video and a Zed board and wonder if I could get some tips. The problems I encountered during my research is: -The picture I take has to be stored ASAP, meaning I have to use the mig7 interface for the SDRAM and HDL code. However this will be hard since it requires me to understand how the MIG7 works and thus writing a HDL that is adjusted to work with it. - What is the maximum frequency of a micro blaze? Using the micro blaze would be easier for me since I can directly write and read to/from the SDRAM using the peripheral libraries. However, the maximum clock frequency of a MB processor is not so much thus making that choice a bottleneck. - How should the communication between the camera and the SDRAM work? My initial idea was to use a buffer (BRAM) and store my picture there and then somehow do pipelined reading using the micro-blaze. Or alternatively, to send bytes to the micro-blaze directly without using a buffer. However I don’t really know if that is a good idea since the camera and the micro blaze work on different clock frequency levels. Would be glad if you could help me on the way. Regards, John
