The (theoretical) MMIX architecture that Knuth books use has a register-stack.
- p_l 6y agoIt's a mechanism from few real-world RISC cpus that was used in MMIX, i.e. register windows which form a stack (RISC cpus otherwise usually didn't have a stack other than by convention). One CPU that used that approach was SPARC, although the difference is that MMIX has variable-length windows.
