The company is packing Altera Arria 10 FPGAs along with its Xeon E5-2600 v4 processors, code-named Broadwell-EP, in a multichip module.
so you take a dice made by tsmc and put it on a substrate next to an x86, connect it with pcie and call this "baking speedy fpgas into chips" ? cool.
if you want to see how this is done properly, checkout what's called zynq ultrascale+. while you are at it check if altera has managed to tape-out a stratix 10 on intel 14nm process; a chip which has been announced almost three years ago now.
