Memory management is the process by which a computer system allocates a limited amount of physical memory among the various processes that need it - such as operating system or application calls ...

One method of memory management is known as paging . Memory is broken up into fixed-size blocks, known as pages . Different operating systems allocate their own size to pages.

In this installment, the author describes the various techniques used for memory management in an embedded OS. Adapted from “Embedded Systems Architecture, 2nd Edition” by Tammy Noergaard (Newnes) 9.3 ...
