  1. Computer Organization and DesignWrap Up! Montek Singh Dec 6, 2017

  2. What else can we do? … to improve speed?

  3. Multicore/multiprocessor • Use more than one processor = multiprocessor • called multicore when they are all on the same chip • read all about it in Chapter 6 of textbook

  4. GPUs for data-intensive tasks • Originally developed for graphics • Now rapidly gaining importance for general-purpose computing • Main advantages • Massively data-parallel • Fast memory architectures

  5. Nanotechnology • Nanoelectronics • DNA based self-assembled electronics • Use DNA to fabricate tinier transistors than possible today using laser/lithographic techniques

  6. Energy-efficient design • Many many research directions… • A new and very interesting one is “energy harvesting” • Smart home: Internet-of-Things

  7. That’s it folks! So, what did we learn this semester?

  8. What we learnt this semester • You now have a pretty good idea about how computers are designed and how they work: • How performance is measured • How data and instructions are represented • How arithmetic and logic operations are performed • How ALU and control circuits are implemented • How registers and memory are implemented • Lots of lower-level programming experience: • C and MIPS • This is how programs are actually executed! • This is how OS/networking code is actually written! • Java and other higher-level languages are convenient high-level abstractions. You probably have new appreciation for them!

  9. Where to go from here? Courses you can take in the future: COMP 541: Digital Logic and Computer Design COMP 740: Computer Architecture [grad]

  10. Final Exam? Grades? We are trying to wrap up all grading! Final Exam is on Tue, Dec 12, 12-3pm Also, don’t forget to submit your course evaluation!

  11. Final Exam • Material covered: • Everything, but more emphasis on post-midterm material • Open-book, open-notes, calculator allowed • Laptop required: • Answers will be entered in Sakai (as in the midterm) • Sample questions (from past exams) on website • Date/time: • Tue, Dec 12, 12-3pm

  12. Grading • Lab X (mini project) • scores will be available by the final exam • Lowest drops • Sakai already has been set up to drop • lowest 2 labs (amongst Labs 1-9only) • lowest 1 homework; lowest 1 quiz • Some of you are missing some scores • will be eventually set to 0 for non-submission • Letter grade cut-offs • Will only move lower (in your favor) if at all, but not higher

  13. Good luck for all your finals! Do not forget to submit your course evaluation!
