Which are the choices to learn about network message processing in FPGA? I would like to get a couple of FPGA cards, to allow students to learn about low latency network message processing. My assumption is that the Ethernet port must be connected directly to the FPGA. Is this correct? If that is correct, then it seems that low cost solutions like the Arm based Zinq are not appropriate, as the network port is connected to the ARM CPU, and not directly to the FPGA. So far, the only card I could find where this 'direct connect' is stated, is the NetFPGA 1G card, at around 1,500 usd, Are there any lower cost options?
