From whence cometh the name “Translation Lookaside Buffer”.
Why “lookaside” ? It turns out when the idea was invented,
caches were rare, and were oft referred to as “lookaside buffers”,
so the translation cache was called a “translation lookaside buffer”.
The name stuck.
(I found this shortly after midnight one night, when I just cracked
open my copy of Dominic Sweetmans MIPS book, “See MIPS run”. I was
just, you know, reading casually, procrastinating doing real work.
Somehow I wound up on page 121 and voila, who’d a thunk it ?)
