Ah, my old field of study. I spent decades doing work on FPGA computing. An area that refuses to die (but also refuses to be successful). This would be the old Altera FPGAs, which Intel has been selling for quite some time, but aimed at the data center. I like this idea and I think it could be taken much further. I will note that the URL calls this a “smart NIC” which, I suppose, is one way to look at it.
