Review of Combinational Logic

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!

What is a Computer? 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

Not JustThis!

Types of Computers In this course, a “computer”

could be anything from the simplest embeddedmicroprocessor…

…to the largest supercomputer! We will discuss architectural

techniques 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)

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?

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.

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:

Grading Category Undergrads Grads

Attendance and participation 5% 5%

Homework assignments and small projects 10% 10%

Short papers (U) or research project (G) 5% 15%

Midterm Exam #1 25% 20%

Midterm Exam #2 25% 20%

Final Exam 30% 30%

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!
