(BIBOP) Where data objects are tagged with some kind of descriptor (giving their size or type for example) memory can be saved by storing objects with the same descriptor in one page of memory

The most significant bits of an object's address are used as the BIBOP page number

This is looked up in a BIBOP table to find the descriptor for all objects in that page

This idea is similar to the zones used in some Lisp systems (e

g

LeLisp)
