Introduction to CS554 Real-Time and Embedded Systems

This course introduces the design requirements, timing constraints, and key concepts of real-time and embedded systems. It focuses on timing and quality-of-service issues, while also addressing power and reusability concerns. The course covers real-time scheduling, operating systems, databases, web servers, multimedia QoS management, communication, and wireless sensor networks.

  3. Real-Time Embedded System Design Requirements • Timing constraints • Not only functional correctness but also timing matters • Hard real-time vs. soft real-time • A deadline miss incurs a catastrophic result in hard real-time systems • Other key requirements • Cost, size, power, time-to-market, reliability/safety… • Focus on timing and QoS issues, dealing with power & reusability issues as time permits
