Embodiments of the inventive subject matter generally relate to the field of computers, and, more particularly, to controlling access to memory space of a computer.
On conventional operating systems, the physical memory space is usually protected in accordance with segmenting and/or paging. With memory segmenting, a memory is protected by enforcing permissions of a segment against a process. With paging the same physical memory can be reused by different processes and users. The decision of which processes to map to which physical memory segment is done by a memory manager of the operating system.
