Wave Computing Adopts Low Power MIPS 64-bit Multi-Threaded Core
Wave Computing [...] announced today that it has selected a 64-bit Multi-Threaded processor core from MIPS Technologies for future AI solutions. Wave will use the MIPS core in its next generation of Dataflow Processing Unit (DPU) chips that will ship in Wave's future deep learning systems to handle device control functions including management of the real-time operating system (RTOS) and system-on-chip (SoC) subsystem.
As design complexity and software footprints continue to increase, the 64-bit MIPS architecture is being used in an even broader set of datacenter, connected consumer devices, networking products, and emerging AI applications. In addition to Wave, companies including Mobileye, Fungible, ThinCI, and DENSO, among others, are using the MIPS 64-bit processor core as they develop ground-breaking AI applications. [...] Last August, Denso group company NSITEXE, Inc. announced that it licensed the newest MIPS CPU to drive enhanced in-vehicle electronic processing.

FYI Last I checked your typical x86-64 can't address more than 48bit directly or 52bit with PAE.
Just some pointless trivia...

And often underappreciated. Most operating system level code is going to have to be rewritten when that gets expanded out, and given that everything bit 52 and above is used means that there might be userspace code out there that actually DOES either poll or filter those bits, meaning old code may need some major rewrites to work with full 64 bit addressing. Honestly I dislike the fact that they call them 64 bit processors without more clearly defining if they mean 64 bit addressing, or simply 64 bit integer processing.

Operating systems are ready for full 64-bits since the beginning of amd64 support. There is no reason to implement any type of filtering in "userspace code" since it never does see the underlying physical address (every process has its own virtual address space). I'd suggest you look into how an operating system works in terms of memory management, it might be useful...

The CPU insists that those unused bits remain zero (rather than just ignoring them like a 68000), so people wouldn't be tempted to put random garbage in there that would only cause problems in the future.

Pointless and incorrect. There is no PAE for amd64. You're thinking of virtual and physical address spaces. Neither is truly 64-bit wide in any current implementation.
