3. Goals The course goals to provide students with: –The skills and knowledge needed to better understand embedded computing systems and to initiate original research in this domainThe skills and knowledge needed to better understand embedded computing systems and to initiate original research in this domain –Gain experience in designing and evaluating embedded processor architectures and microarchitectures.Gain experience in designing and evaluating embedded processor architectures and microarchitectures. –An understanding of compiler and run-time software for embedded systems.An understanding of compiler and run-time software for embedded systems. –An opportunity to research embedded computing systems through a class project and presentation.An opportunity to research embedded computing systems through a class project and presentation.

4. Course Description Examines recent research in high-performance embedded computing systems –Emphasis on embedded processor architectures and microarchitectures –Also covers embedded system design and simulation, embedded compilers and tool chains, run-time systems, and application design Places a large emphasis on –Reading and discussing research papers and textbook material –Working through practical examples Homework and a course project used to help you put the ideas from the course into practice

10. Lectures, Homework, Quizzes It is important to attend each lecture –Lots of the material covered in lecture is not in the book or readings There will be several homework assignments –Not all will be collected/graded –May require use of C/C++ and Unix –Due at start of class –Late homework not accepted There will be unannounced in-class quizzes –Lowest score dropped to accommodate occasional absence

11. Project [1] For the course project, you will be expected to complete original work related to embedded systems in teams of three or four students. Projects will consist of a proposal, status report, final report, and short presentation. You are encouraged to come up with your own topic for the project, but will be provided with a list of possible ideas. Projects can consist of an in-depth survey, original research, and/or hardware or software development related to embedded systems.

12. Project [2] The class project counts for 30% of the overall grade. Students will be expected to turn in a summary of the contribution to the project to facilitate fair grading to individual team members. Additional details on the course projects will be provided in a separate document.

13. Other Items Plagiarism: using someone else’s ideas, words, figures without proper acknowledgement –Is illegal and not allowed in this class –Be sure to phrase statements in your own words and cite appropriate references directly in the text –Failure to do so will result in severe grading penalties Communication: –Questions and comments during class are encouraged –I encourage you to meet with me during office hours –I will frequently email the class –When sending email include ECE751 in subject
