Revivified MIPS
Interesting how far they can push this design. Its a MIPS ISA plus extensions but the basic design of MIPS is pretty ancient by any standard (all the Silicon Graphics (SGI) workstations had MIPS processors.)
I would have thought a more recent design (which is just about any: Arm, Alpha, Sparc, Power, PA-Risc) might have been a better starting point - even Risc-V. Revisiting the transputer might too be worthwhile.
May well be a case of its good enough for general computing needs - even Windows appears to have exhausted its reservoir of crap ideas with which to squander cpu cycles but AI/ML can help out there ;)
