Real-Time Systems: Scheduling, Analysis, and Verification by Prof. Albert M. K. Cheng (Publisher: John Wiley & Sons), 2nd printing, 2005.
TA: TBA

Synopsis:
The monitoring and control of physical processes and systems are increasingly performed by computers. These real-time embedded systems must satisfy stringent timing and reliability constraints in addition to functional correctness requirements. Examples of these embedded systems include the new generation of airplane avionics, the planned Space Station control software, high-performance network and telephone switching systems, medical monitoring instruments, multimedia tools, virtual reality systems, robotic controllers, PDAs (running Pocket PC, Palm OS, and Linux Embedix OS), and wireless phones. This course introduces a formal framework and powerful techniques for the design and development of this class of systems. These theoretical foundations are followed by hands-on practice in employing these advanced techniques to build, analyze, and verify different modules of actual real-time systems. Scheduling tools (such as Rapid RMA, PerfoRMAx, and TimeWiz) and OSs (such as VxWorks) are introduced. Tornado development tools are used in projects. Programming in real-time/rule-based languages such as Ada, EQL, MRL, and OPS5 is described. Specification and verification tools such as Statechart, Modechart, and Estella are used to help design experimental real-time systems. Embedded programming techniques are studied. The course also serves as a forum for discussing state-of-the-art research topics in real-time systems design.
