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 Statck 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.

*A great introduction to real-time systems including general concepts and terminology
*An insider shares his knowledge on ThreadX 5, a real-time operating system
*A limited version of the ThreadX 5 software is packaged on a CD-ROM with the book
to run all sample projects and the case study

Get up to speed with the ThreadX 5 real time operating system - deployed in over 500
million devices worldwide including cell phones, digitial cameras, and laser printers!
