  1. ComputerArchitecture EEL 4713/5764, Spring 2006 Dr. Michael Frank Module #1 - Introductory Lecture

  2. Introductory Lecture • Overview of Computer Architecture • What’s it all about? • Course Administrative Matters • Overview of Syllabus, Course Objectives • Grading Policies & Procedures • First Homework out – Due next Wed. • (Time Permitting) Begin Chapter 1 • Review of Combinational Logic

  3. What’s Computer Architecture? • Architecture (in general) = • Design of a functional structure • Computer Architecture (CA) = • Design of the logical structure and functional organization of a computer system. • Especially its CPU and associated components • Computer Architecture does not traditionally include other aspects of computer system design… • Enclosures, styling, packaging, applications, power supplies, cooling systems, peripheral devices… • But these are all important in designing real-world products!

  4. What is a Computer? Not JustThis! • A computer is (most generally) any information processing system! • Today, this almost always means a digital system… • Though simple analog “computers” do exist… • Also, today we usually mean a general-purpose, universal, or at least programmable computer • Although a wide range of non-programmable digital components exist that perform fixed functions • These could be considered simple special-purpose computers Medievalastrolabe

  5. Types of Computers • In this course, a “computer” could be anything from the simplest embeddedmicroprocessor… • …to the largest supercomputer! • We will discuss architecturaltechniques for parallelcomputing if time permits… Intel 4004 (1971)(4-bit, 740 kHz) IBM Blue Gene/L (2005)(65,536 processors, 136 TFlops, 1MW, 300 tons)

  6. Levels of Computer Architecture • Computer architects may deal with design elements at a variety of different levels… • Custom logic circuit & functional-unit designs. • CPU datapath pipelines, memory hierarchies. • Instruction-Set Architectures (ISAs) • Or other programming models. • Special compiler & operating system support. • Multiprocessing systems, interconnection networks, distributed systems...

  7. Levels of Design & Abstractions Useful Real-World Products HW/SW interface Application Programs Programming Languages } Instruction Set Architecture (ISA) Computer Architecture Processor microarchitecture Hardwaredescriptionlanguages Functional units Boolean Logic (the digital abstraction) Logic gates (building blocks) Device Structures (floor) Manufacturing Process (foundation) Physics of the Universe (bedrock)

  8. Processor example:Intel Itanium 2(McKinley) 64b Processor • 221 million transistors! (~US adult population) • How are they used? • What will we do as transistor counts grow? • Most of chip is used formemories, inst. decoding,dynamic scheduling… • Why is it done this way? • How much more efficient could it be if more of area went to actual processing?

  10. Course Administrative Matters • Go over syllabus: • Objectives, Outcomes, Grading Policies • Go over course website: • Slides, Assignments, Submission Procedures • First homework available right after class! • Covers Ch. 1: Review of combinational logic. • Due next Wednesday, BEFORE CLASS

  11. Course Instructional Objectives (CIOs)

  12. Program Outcomes (POs) and The Course CIO-PO Matrix • Program Outcomes: Students graduating from the BSEE and BSCpE programs will have: • (a) Apply: An ability to apply knowledge of mathematics, science, and engineering; • (c) Design: An ability to design a system, component, or process to meet desired needs; • (e) Solve: An ability to identify, formulate, and solve engineering problems; • (i) LLL: A recognition of the need for, and an ability to engage in life-long learning; • (j) Contemp.: A knowledge of contemporary issues; • (o) Topics: (EE) A knowledge of electrical engineering applications selected from the …digital systems… areas. (CpE) A knowledge of computer science and computer engineering topics including … computer architecture. • Each outcome is assessed through… • 3 = an examination or quiz problem requiring individual effort by the student. • 2 = a HW assignment, project assignment or laboratory experiment requiring group effort.

  13. Grading Scale & Weightings • Scale: A ≥ 90%, B ≥ 80%, C ≥ 70%, D ≥ 60% • Rigid; no curves, exceptions, or rounding! • The overall course grade is determined as the weighted average of the following items:

  14. Your Assignment for Today is… • Sign the attendance sheet before you leave. • Sign and turn in a prerequisite form before you leave. • Get the textbook from the bookstore ASAP. • Get on the course’s Blackboard site ASAP. • Download homework #1. • Do it by next Tuesday!
