Chapter 8
Memory-management algorithms for multiprogrammed operating systems
range from the simple single-user system approach to segmentation and
paging. The most important determinant of the method used in a particular
system is the hardware provided. Every memory address generated by the
CPU must be checked for legality and possibly mapped to a physical address.
The checking cannot be implemented (efficiently) in software. Hence, we are
constrained by the hardware available.
