Department of Electrical and Computer Engineering What is Electrical and Computer Engineering? Professor Charles Kime, ECE Associate Chair for Undergraduate Activities

Overview A Lifetime of Change: What is Electrical and Computer Engineering? Electrical Engineering (EE), Computer Sciences (CS), or Computer Engineering? Education and Careers Specialized Areas of Study

A Lifetime of Change What we didn’t have when I was born (1940) –Transistors, integrated circuits, microprocessors –Computers, personal computers –Televisions, VCRs, CDs, Nintendo –Satellite communications –Internet, , world wide web –Cellular Phones –Jet Airliners

A Lifetime of Change II What we did have when I was a college student (1961) –Transistors, integrated circuits (barely) –Television –Mainframe Computers (tubes, core memory) –Jet Airliners

Where did all this stuff come from? engineering (Webster’s dictionary): The application of scientific knowledge to the solution of practical problems, as in designing structures and apparatus.

Computer Engineering Computer – A combination of software and hardware capable performing useful tasks. The Obvious: PCs/Workstations/Servers/Mainframes The Not So Obvious: Embedded Computers – Computers within Other things! Examples? Computer Engineering = Engineering of Computers Problem-solving with the goal of creating software, hardware or combinations of hardware and software to perform useful tasks.

Electrical Engineering Electrical – Use of electricity to performing useful tasks. Electrical Engineering = Engineering of All Things Electrical Problem-solving based on mathematics and science with the goal of creating new electrical and electronic hardware and systems to perform useful tasks.

Relationships: Software Hardware Computer Sciences Electrical Engineering EE, Comp Sci, or CMPE ? Computer Engineering

Comp Sci versus EE, CMPE at UW Computer Sciences Focus on Software More Scholarly Breadth Less Technical Content and Technical Problem- Solving Somewhat Less demanding overall program Electrical Engineering, Computer Engineering Focus on Hardware or Hardware and Software More Technical Content and Technical Problem-Solving Less Scholarly Breadth Somewhat more demanding overall program

EE versus CMPE at UW Electrical Engineering Primary focus on hardware, but some areas have significant software component Stronger emphasis on device physics, analog systems, and energy Involves more physically oriented courses Computer Engineering Focused on a balanced mix of hardware and software Stronger emphasis on software, digital systems, and computers Involves more digitally- oriented courses in hardware, software or both

How do I decide between EE, CMPE or Comp Sci ? What area am I interested in specializing in, an EE area, a CMPE area, or a CS area? –Databases? Control Systems? Network Design? What topics do I do well in and enjoy? – Programming? Calculus? Physics? What overall degree environment fits me better –Engineering? Letters & Sciences? Which degree program is most marketable? – All! Do I have geographic preferences for jobs?

What if I make the wrong decision? Transfer between the EE and CMPE programs is not difficult In the transfer process, you may lose some credits toward your degree, but not many Due to more limited capacity admission standards for CMPE may be higher Transfer to and from CS more complex

Roles of Electrical and Computer Engineers Analyze, design, develop, market and operate electrical/electronic/computer systems Work with energy and information Invent new technologies and improve existing technologies Many graduates take positions in companies like Intel, IBM, Motorola, GM, and Qualcomm

Desirable Traits Interested in mathematics, physics, and science Scientific curiosity and the desire to understand how things work Desire to learn continuously Good communication skills Good team player Persistent, but flexible

Education Bachelor of Science (B.S.) degree ( 4 years) in EE or CMPE For more in-depth knowledge: Master of Science (M.S.) degree (1.5 to 2 years)—not necessary for first job For research and college teaching: Doctor of Philosophy degree (3 to 5 years) Opportunities exist to spend summers (intern) or half-year (co-op) in industry

Current Starting Salaries B.S. degree and no experience—$48,000 per year M.S. degree and no experience—$55,000 per year Ph.D. degree and no experience—$70,000 or more per year Signing bonuses and stock options in some areas

Advancement Opportunities Advancement in industrial jobs is based on performance Excellent opportunities to advance Many engineers end up in management roles

Future Demand Technological, global society demands more and more engineers Computer engineering: 250,000 openings in US Electrical engineering: 197,000 openings in US companies visited Engineering Career Services last year looking for new electrical/computer engineers

Read and answer . Finish a design for a controller using a hardware description language (HDL). Read and answer . Attend an hour long meeting to discuss changes in the interface of the designer’s part of the chip to other parts with the design team. Go for a run and then to lunch. Read and answer . Write a set of test inputs to verify the HDL version of the controller. Read and answer . Meet with another team member to discuss a design problem. Begin controller simulation using the test inputs. A Day in the Life of an Integrated Circuit Designer 7:30 AM Arrive at cubicle and log in to workstation. 6:30 PM Log out and go home.
