You cant fit a Stratix 10 on a nVME stick... Ive tried. Kintex or Arrria is about as big as you can get. Damn 22x80 form factor.
I know.
I question the need for ultra large and expensive FPGAs instead of clusters of smaller FPGAs with high speed interconnects.
Perhaps a custom PCI-E format board with 4-6 last generation FPGA devices with some fast memory and a cross point switch. Are there many individual components of the Xnn series of algos which won't fit on an arria or even a cyclone ?
