About this ebook

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

• Explains the principles of RTOS and shows their practical implementation
• Demonstrates how to prototype a real-time design
• Code is fully available for free use
