How can I connect multiple FPGA and send large data back and forth?
Let's say I have 4 identical FPGA boards running. They are doing some neural network calculation. All of them need to send/ receive data from each other back and forth and do their own calculations using that data. What is the best way/ IP/ protocol to do data transfer between multiple FPGA boards? Thanks.

That is a simple question with a complex answer, RS232 at TTL levels between the boards is easy to implement, but if you have larger bandwidths you may need to take a look at parallel protocols. It also depends on your topology. Maybe just a big parallel bus with a clock and handshake signals.
