Forty year old write-up on VAX/VMS virtual and physical addressing from IEEE Computing, for those interested in (old) virtual memory system designs:
Old While each architecture can have its own unique vietual addressing features and its own wrinkles, even forty years on this stuff all still works basically the same way.
And theres usually a great big must-be-zero hole in the middle of virtual and physical address spaces until right around the same time that vendors work on new processor architecture designs and new architecture extensions begins in earnest.
Right now, nobody really wants to buy 52-bits (ARMv8.2-LPA) or 57-bits (Intel x86-64 5-level) of physical memory, either.
There have been a few systems with a virtual address space smaller than their physical address space, but that has been rare. (e.g. VAX XPA extended physical addressing offered 34-bit physical, with 32-bit virtual.)
And for completeness, here is DEC Standard 32, the VAX Architecture definition:
This copy of DEC Standsrd 32 is eight years newer than the article above, too. This refers to XPA and the never-completed VVAX Virtual VAX designs for instance, where the article does not.
