Recent advancements have not only refined core functions such as memory management and process scheduling but have also embraced emerging paradigms in virtualisation, real‐time responsiveness ...

This excerpt offers a introduction and review of embedded operating systems. Adapted from “Embedded Systems Architecture, 2nd Edition” by Tammy Noergaard (Newnes) Some embedded OSs provide memory ...

Most operating systems, including Windows, have a concept of memory-mapped files. Memory-mapped files allow the creation of pages of memory that correspond to specific named files in the filesystem.

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.

The operating system determines how much memory the program requires, and allocates enough pages to hold it and its documents. When the program is closed, the allocated pages are freed up for use ...

Embedded systems such as Internet of Things (IoT) devices and single-board computers possess limited memory and processing ...
