This is the heart of modern real-time operating systems (RTOS). Priority-driven systems assign priorities to tasks, and the highest-priority ready task always runs. The book explores the two primary branches:
Real-time systems must manage shared resources without causing priority inversion, where a low-priority task blocks a high-priority task. Liu covers: Priority Ceiling Protocol 4. Real-Time Communication

When multiple tasks share data or hardware resources, high-priority tasks can become blocked by low-priority tasks—a dangerous phenomenon known as .Liu provides a comprehensive analysis of protocols designed to mitigate this issue, including: Priority Inheritance Protocol (PIP) Priority Ceiling Protocol (PCP) 6. Multiprocessor and Distributed Systems

Jane W. S. Liu’s Real-Time Systems remains a classic text. While modern systems have evolved, the fundamental theorems regarding priority-based scheduling and resource sharing explained in this book remain the bedrock of modern Real-Time Operating System (RTOS) design. It is an essential read for anyone serious about understanding how computers control the physical world.
The hardware elements required to execute tasks.
Do not skip the reference models. Understanding the vocabulary of release times and deadlines is vital for the rest of the book.
Despite being published initially in 2000, the mathematical proofs and algorithmic foundations laid out by Jane W.S. Liu remain foundational to modern computing paradigms:
Before the rise of multicore processors and cloud-edge computing, real-time theory was a fragmented field dominated by proprietary white papers and complex mathematical proofs. Jane W. S. Liu, a pioneering computer scientist at the University of Illinois at Urbana-Champaign, did the impossible: she synthesized chaos into clarity.
A significant portion of the book is dedicated to how RTOS should function. This includes:
