An intelligent memory subsystem has been implemented, autonomously supporting memory virtualisation. The subsystem directly interfaces the central processing unit with capability-based addressing features described in a previous letter. It is capable of obeying a set of commands, constituting low-level memory management mechanisms; these commands make it possible to state and dynamically change the portions of virtual space actually implemented in the physical memory.
