It is possible. You can write some software on the computer (look at the python CORR package) that checks to see when the accumulator is done, copies the data from the accumulator, and outputs/processes it in some way. The only problem with this approach is that it is slow. You will have to accumulate for a long time (seconds) to be able to leave enough time to copy all the data from the accumulator and output it. The first generation ROACH boards ethernet connections are also only guaranteed to work at 100Mb/s due to issues with the ethernet module. This will make your system even slower. However, if this slowness is not a problem then this is the cheapest and easiest option. Regards Andrew
