1 Modeling an Operating System Kernel
... We show how to develop from scratch an easily understandable, accurate highlevel view of an OS kernel. The model we propose is algorithmic in nature and can be understood without prior knowledge of formal methods. It can be used by lecturers for teaching the principles of OS design and by practition ...
