Course Goals:

The course provides the opportunities for students to learn major issues in Real-time Computing. The main subjects to be discussed in the course are scheduling and model-base development. The goals are:

1.     To understand and be skillful in the analysis of scheduling algorithms for real-time computing, including the techniques to evaluate worst-case delays and utilization bounds.

2.     To be able to apply model-driven development approaches to construct target execution environment for simulation analysis and rapid prototyping, and to verify real-time requirements.

Prerequisites 

1.      CSE230 Computer Organization

2.      CSE420 Computer Architecture I

3.      CSE 430 Operating Systems
