SE 3910 - Real-Time Systems

3 lecture hours 2 lab hours 4 credits
Course Description
This intense design course introduces students to software development for real-time systems, which often have stringent timing constraints that must be satisfied even under adverse circumstances. Real-time applications include flight control systems, vehicle control systems, industrial processes, life-support systems, robotic manipulators, and multimedia applications. Special attention is paid to scheduling, latency minimization, bandwidth constraints, and other design issues that impact the design of these systems. Laboratory assignments provide experience in the design and implementation of realistic applications using a real-time operating system and embedded development board. (prereq: (CS 2711  or CE 1921) , and (CS 3840  or CS 3210 ), or consent of instructor)
