Network example is wasteful. There are already NICs that have FPGA and a whole set of linux's kernel features. You wouldn't want that to be that far away from the NIC itself.

PTP works just like that - timestamps incoming and outgoing packets right after/before packet hit the wire. There is eXpress Data Path that can offload eBPF programs to NICs and deal with packets without them even coming into even kernel at all.

High Frequency Traders do exactly that IIRC today.

As for video processing codecs today are way too complex to be run there. Well, no one will stop you from running something like an integer DCT part on FPGA.

VR thing... Generally, aside from Nvidia companies don't want to ship entire FPGA to end customers (guess why Nvidia G-Sync monitors used to be so expensive). Something like Snapdragon XR2 "solves" VR. Also, in order to render a picture you need to know headset position early, not at the last moment. How would you know what to render?

How useful is the subject depends entirely on FPGA capability, and it's size. I bet it will be more useful for things like implementing some hash function there or something like that.

IMO this will be a very niche product inside already niche market.
