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 domain – Gain experience in designing and evaluating embedded processor architectures and microarchitectures. – An understanding of compiler and run-time software for embedded systems. – An opportunity to research embedded computing systems through a class project and presentation.

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 real/practical examples Course project used to help you put the ideas from the course into practice

Course Textbook and Tools There is no required textbook for the course – We will rely on readings from the literature Useful reference texts include – Wayne Wolf, High-Performance Embedded Computing, Morgan Kaufman Publishers, Elsevier, 2007. Textbook Website: http://www.waynewolf.us/hiperf-book/ Joseph A. Fisher, Paolo Faraboshi, and Cliff Young, Embedded Computing: A VLIW Approach to Architecture, Compilers and Tools, Morgan Kaufman Publishers, Elsevier, 2005 – Wayne Wolf, Computers as Components: Principles of Embedded Computing System Design, 2nd Edition, Morgan Kaufman Publishers, 2005. – John L. Hennessy and David A. Patterson, Computer Architecture: A Quantitative Approach, 4th Edition, Morgan Kaufmann Publishers, 2006.

Course Research Papers About 30 research papers will be assigned – Typically two per week – Available from the course website – Read before coming to class & be ready to discuss Subset of papers must be reviewed in writing – Typically one per week – Review due dates will be posted on course website: typically the night before scheduled class discussion – Reviews must be uploaded to learn@uw dropbox

Research Paper Presentations Each student will be asked to lead discussion on a research paper Prepare 15-minute talk w/slides – Thoroughly understand, describe paper – Read 6-10 additional papers for full context For newer papers, primarily citations from the paper For older papers, also include newer papers that cite this one (find using Google scholar, ACM digital library, IEEE Explorer) Excellent practice for ECE PhD Qualifier

Course Grading [1] Paper reviews and discussion: 25% Paper presentations: 15% Final exam: 20% Course Project: 40%

Course Outline Introduction – Course introduction – Embedded system design goals – Categories of embedded processing Review of CPU concepts (please fill out survey) Microarchitectures for high-performance/low-power embedded computing Embedded software Memory architecture for high performance embedded computing Embedded Multiprocessors Accelerators and peripheral processors Design and Modeling tools and methodologies

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.

Project [2] The class project counts for 40% 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.

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
