  1. CS 433:Computer System Organization Prof. Luddy Harrison Lecture 1 CS 433 Luddy Harrison

  2. Administrative Matters • Professor: • Luddy Harrison • 4108 Siebel Center • luddy@uiuc.edu (please use this) • Office Hours: by appointment (send me email) • Teaching Assistants: • Lin Tan • lintan2@cs.uiuc.edu • Office Hours and location will be on the web site • Textbook: • John L. Hennessy and David A. Patterson • Computer Architecture: A Quantitative Approach (Third Edition) • ISBN 1-55860-596-7 (cloth) • ISBN 1-55860-724-2 (paper) CS 433 Luddy Harrison

  3. Web Site • URL: • http://www.cs.uiuc.edu/class/cs433ug • What you will find there: • Schedule of lectures, homeworks, quizzes, exams • Lecture notes • Links to processor documentation • Policies • The Web Site Is Important • All announcements will be made there • It will be online by Sunday evening Sept 27 CS 433 Luddy Harrison

  4. Policies: Grading • Homeworks will be lightly counted • Quizzes will be every other Tuesday beginning Sept 6 • They will cover the previous homework material and lectures • Roughly speaking: if it’s not in the lectures, it won’t be on the tests or homeworks • If it’s in the lectures it is fair game CS 433 Luddy Harrison

  5. Policies: Cheating • Collaborative work is cheating • You will get a zero on the assignment and a loss of a letter grade if caught • I’m trying hardto take away the motivation for cheating by using quizzes • If you do well on a homework and flag the quiz I will probably ask you to explain CS 433 Luddy Harrison

  6. Make-ups • No quiz makeups • The lowest quiz grade is dropped • This lets you miss a week of class without penalty • In the event of illness contact me. I will probably do nothing unless you miss several weeks of class. • I require a note from the Dean as well as a signed note from a doctor saying that the illness is to serious for you to go to class • A McKinley timestamp thing will not do CS 433 Luddy Harrison

  7. Policies: Attendance • Attendance is not required • Quizzes are every other Thursday starting Sept 8. CS 433 Luddy Harrison

  8. Projects • You can do an extra-credit project • This will change your grade by at most one letter • I’m thinking of visual simulations of processors CS 433 Luddy Harrison

  9. Prof. Harrison’s Grade-Related Sympathy Diagram CS 433 Luddy Harrison

  10. A Note For Special Students • If things are going really badly for you … • You aren’t attending classes or doing your work • You aren’t sure you are in the right degree program, or that you want a degree at all • For some other reason you are down and out • … then you should come see me (really) • No, I won’t give you a good grade! • But I might be able to help you. CS 433 Luddy Harrison

  11. The Book • I will follow it closely concerning • Pipelining • Tomasculo • Cache • Virtual Memory • Otherwise I will not follow it closely • I find it to be old and funky but quaint • If I don’t lecture on material, it will not be tested or homeworked or quizzed CS 433 Luddy Harrison

  12. Goals and Focus • Processor Architecture • Therefore dropping CA:AQA Chapters • 7 (Secondary Storage) and • 8 (Interconnects) • Mechanisms for Performance • Parallelism • Pipelining • Data parallelism • ILP • Static • Dynamic • Multithreading • Multiprocessing • Reduced Memory Latency / Increased Memory Bandwidth • Caching • Latency Hiding • Wide Memory Interfaces • Current Processors as Examples (this list is only preliminary) • MIPS (general purpose, embedded control) • ARM (low-power general-purpose, e.g., PDAs) • Intel IA32 (x86) (general purpose, embedded control, almost everything) • IBM PowerPC (general purpose, embedded control, network processing) • TI TMS320C6000 (C6x) (high-performance media and signal processing) • ADI TigerSharc (cellular infrastructure, software radio) • Intel IXA (network processing) CS 433 Luddy Harrison

  13. Skills You Will Develop • Know the major classes of processor type • What characterizes each in terms of • Programming Model / Application • Structure • Performance • Grasp a new processor architecture quickly • Size it up in terms of • Programming Model / Application • Structure • Performance • Compare it intelligently to its ancestors • Reason about processor and system performance • Quantitatively (CA:AQA) • Qualitatively and Intuitively CS 433 Luddy Harrison

  14. What Kind of Person is a Computer Architect? • Expert in target application domain • Expert in circuit / logic design and highly proficient with CAD tools • Good engineering team leader • Can inspire others to follow • Can promote and explain ideas tirelessly • Can talk well with • Customers • Co-workers • Investors, sponsors, etc. • Can organize work for others • Knows the history of computer architecture • What has been done before • What worked and did not work, etc. • At least for the processor type under consideration, but most commonly for many types of processors CS 433 Luddy Harrison
