Memory management unit-a new principle for LRU implementation
G. Stefan, F. Draghici · 2002
A new principle is presented for a memory management unit (MMU) which contains a new circuit for LRU (least recently used) implementation. A MMU has been chosen for study. It works with a 24-b address processor for which it facilitates access to a virtual memory (VM) of 16 Mwords, available on a disk, through the assistance of a paginated dynamic primary memory (PM) of 1 Mword, which keeps the most recently used (MRU) pages.>
