Design of Process Management for Multi-Process Micro-Kernel Embedded OS on ARM

Abstract

This paper describes the design and implementation of process management for ARM based multi-process micro-kernel embedded operating system in technical details, including allocation of process memory space with MMU, creation of system level tasks, generation of the init process, the process management task, switching of the tasks and processes, and multi-level priority-queue schedule. The paper finally gives a demo example to show the performance of the process management. The entire operating system is implemented on Linux with GNU tool chain by the author of this paper, which is programmed simple and compact therefore suitable for both embedded system development and embedded related curriculum teaching in colleges and universities.
