Real-Time Embedded Multithreading contains the fundamentals of developing real-time operating systems and multithreading with all the new functionality of ThreadX Version 5. This MIPS edition covers all the new ThreadX 5 features, including real-time event-chaining, run-time performance metrics, and run-time stack analysis as specified for MIPS. ThreadX has been deployed in approximately 500 million devices worldwide including cell phones, digital cameras, and laser printers. General concepts and terminology are detailed along with problem solving of common pitfalls. The features and services of ThreadX are reviewed. The book is technology agnostic and applicable to all types of microprocessors.

Key Features
