What surprised me was that this entire walk is fully hardware-driven -- no microcode involvement at all. The state machine reads the page directory entry, reads the page table entry, checks permissions, and writes back the Accessed and Dirty bits, all autonomously. Since it's hardware-driven, it runs in parallel with the microcode and needs its own memory bus arbitration -- the paging unit must share the bus with both data accesses from the microcode and prefetch requests from the instruction queue.
It wasn't apparent in my initial demo, but the new RayNeo glasses are missing some very important features. With my Xreal glasses, I can easily adjust the size of the virtual screen, the angle of the virtual screen, and the distance. I can also activate a curved, ultra-wide display mode. Most importantly, I can anchor the display so that it freezes in a particular part of my eyeline, no matter how much I turn my head.
