Book details. ... For senior/graduate-level courses in Real-Time Systems in Computer Science and Computer Engineering departments. Target Audience
Classifications of software routines based on how frequently they repeat and how predictably they arrive. 2. Clock-Driven Scheduling
An overview of clock-driven, weighted round-robin, and priority-driven approaches. This chapter highlights the trade-offs between predictability and system flexibility. 4. Clock-Driven Scheduling
Jane W.S. Liu’s text is widely praised for its rigorous, mathematically sound approach to solving these timing predictability challenges. Core Concepts Covered in the Text
In the field of computer science and embedded engineering, stands as the definitive textbook. Originally published in 2000, this foundational text bridges the gap between academic theory and practical engineering. It remains a staple on the syllabi of top-tier universities worldwide.
Liu introduces a standardized reference model to describe real-time workloads. This model relies on three main pillars:
Liu tackles the complexity introduced when tasks share resources (like memory or I/O ports). She explains how blocking times caused by semaphores and mutexes can break the mathematical guarantees of scheduling theories and how to account for this blocking in analysis.

However, the book is not without its critiques. Some reviewers note its focus is "traditional" and "theoretical," focusing heavily on hard real-time scheduling. They point out that more modern issues, such as the use of time-triggered systems, are given little to no coverage, and that the examples, while clear, are often abstract rather than grounded in real-world applications. It is also often described as "not for beginners," requiring a dedicated and careful reading to fully grasp the concepts.
