Embedded RTOS Design: Insights and Implementation

by Colin Walls

Overview

Embedded RTOS Design: Insights and Implementation combines explanations of RTOS concepts with detailed, practical implementation. It gives a detailed description of the implementation of a basic real-time kernel designed to be limited in scope and simple to understand, which could be used for a real design of modest complexity. The kernel features upward-compatibility to a commercial real-time operating system: Nucleus RTOS. Code is provided which can be used without restriction.

Gain practical information on:

• Scheduling, preemption, and interrupts
• Information flow (queues, semaphores, etc.) and how they work
• Signaling between tasks (signals, events, etc.)
• Memory management (Where does each task get its stack from? What happens if the stack overflows?)
• The CPU context: storage and retrieval after a context switch

With this book you will be able to:

• Utilize a basic real-time kernel to develop your own prototype
• Design RTOS features
• Understand the facilities of a commercial RTOS

About the Author

Colin Walls has over forty years' experience in the electronics industry, largely involved with embedded software - very much a pioneer in this specialty.
He has been a frequent presenter at conferences and seminars including:

• Embedded Systems Conference, San Jose and Boston

• Embedded World, Nuremberg

• Arm Tech Con, California

• Mentor events world-wide

• Numerous partner events

Colin has authored a great many technical articles and one of the first books on embedded software ["Programming Dedicated Microprocessors"; Macmillan Education, 1986]. His most recent publication is "Embedded Software: The Works" [2nd edition; Newnes, 2012], which addresses a wide range of embedded software topics.
He is an embedded software technologist with Mentor, a Siemens business, and maintains a blog at http://blogs.mentor.com/colinwalls. Colin is based in the UK, where he lives with his family. Away from work, his main interests are photography, reading/writing, and food and drink.
