Embedded RTOS Design

Book excerpt: 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
