What’s your point? NPU was mentioned earlier and I routinely see NPU used as an acronym for “neural processing unit” in modern embedded hardware containing hardware either on chip or on module for accelerating neural networks for various edge computing applications of machine learning models.

I’m pretty sure Vector Processing Unit may outdate Video Processing Unit given that people were developing vector processing hardware for high performance computing back before even the Amiga was released which is the earliest thing I can think of that had serious video related hardware. I leave room for someone to have called their text mode display driver chips a “video processing unit” but I don’t think it would have been common given the nominal terminology at the time was to call the screen a “display” and the hardware was typically called a “display adaptor” or “display adapter” … at least in my experience, which I will admit is limited since I didn’t live through it merely learned after the fact by being interested in retro computing.
