Electronic Engineering

1st semester, 2012 ENGG1015 - H. So 2

Extensive. Essential. Extremely complicated.

How to capture the essence of all these in

1 semester?

Course Goal

Selected topics in EEE with depth •  Digital Logic •  Computer Architecture •  Circuit •  Signal & Systems

Techniques useful also in non-EEE disciplines •  Dealing with large

complex systems •  Team project

How complicated? Moore’s law n  “The number of transistors incorporated in a chip will approximately double

every 24 months.”

—Gordon Moore, Intel Co-Founder (1965)

n  Core i7-980 has 1.17 billion transistors, at 3.33 GHz, 32nm technology

1st semester, 2012 ENGG1015 - H. So 4 taken from: http://www.intel.com/content/www/us/en/silicon-innovations/moores-law-embedded-technology.html

If Moore’s Law were to apply to homework n  Assume:

•  10 minutes to solve a homework question with 10 circuit components (level of 1015)

•  Amount of time needed to understand the circuit scales linearly (much worse in real-life)

•  An Intel Core i7 contains ~1 billion components

n  How long does it take to fully understand the processor?

n  Ans:


109 minutes = 694,444 days = 1,901 years

Dealing with Complexity n  PCAP

•  Primitive •  Composition •  Abstraction •  Pattern

n  Break down large problems into smaller pieces

n  Build large system using smaller pieces

PCAP - Abstraction

n  Abstraction is the process of encapsulating (low-level) details by well-defined interfaces. •  Related concepts: layering, sub-system, hierarchy

n  Hiding low-level details allows one to focus on the big-picture (current picture)

n  In simple terms: Make use of something even before you fully understand how it works


Top-Down vs Bottom-Up n  To any problem, an engineer can

either take a top-down or a bottom-up approach.

n  A top-down approach starts with high-level ideas and work downwards towards implementation details •  An onion peeling process

n  A bottom-up approach starts with low-level details and work upward to the final goal •  A building process

n  Good engineering practice combines both methodologies


Bottom Up

Top - Down

High-Level Goal

Low-Level Details

ENGG1015

A Top-Down Approach n  Start from the high-level goal n  Gradually unveil details of next lower-level as

needed

n  Unveil by asking “Why”, “How”.


An Onion Peeling Process

Example: Using Computer n  As long as you know how to use a keyboard and a

mouse, you can be operating the entire computer without knowing: •  How the keyboard is connected to the computer •  How does the keyboard tell the computer which key you

have pressed •  …

n  It works because all the detail communication between a computer and the keyboard are hidden behind a well defined abstraction: •  There are 104 keys. •  Pressing a key è Computer receives the corresponding

value


Peeling the onion… n  One day your keyboard is broken, you need to

replace it with a new one n  As a result, you need to know more details about

the keyboard: •  What kind of connection does it have to the computer?

USB? PS/2? •  Do you want to have a “wireless” keyboard?

But… n  You don’t need to know:

•  How does USB work. •  How does the wireless connection work for the

keyboard. Is it the same as your cell phone?


More Onion Peeling… n  One day you have become a hardware engineer

for a computer accessory company, then…

n  You will need to know how does the USB connection on the keyboard communicate with USB host controller on the computer

Yet…

n  You still don’t need to know how the USB host controller communicates with the CPU


And the process continues…

Course Topics n  Topics divided roughly into 4 modules


Digital Logic

Circuits

Computer Architecture

Signal & System High Level

Low Level

Project Overview n  A key component of this course is your

project performance

n  Engineering is about Problem Solving •  Problem solving skills are best trained through

group project

n  Work with real-life engineering challenges •  Project deadline •  Budget constraints •  Disputes among teammates


What’s the Project About?


Project: Rube Goldberg Machine n  You will build an incredible, amazing,

creative, and fun Rube Goldberg Machine to pop a balloon. •  “A machine designed to perform a very simple

task in a overly complex way.”

n  Must contain a number of required electronic stages, connected in any imaginable ways

n  Rewarded for being •  Creative •  Fun •  Budget constrained •  Time precision

Plagiarism


Absolutely ZERO tolerance in plagiarism

n  For official definition of plagiarism, see: http://www0.hku.hk/plagiarism/

n  Guide to avoid plagiarism: http://aao.hku.hk/fy4/plan-of-study/exa-and-ass/plagiarism/

Plagiarism n  My unofficial definition: “Any copying and/or stealing of materials

and/or ideas from any person other than yourself” is regarded as plagiarism. •  i.e. includes copying work from previous semester, from the Internet,

from your classmates, etc. n  In the case of an individual assignment, you will automatically

get a ZERO mark for the assignment if acts of plagiarism is detected, including, but not limited to homework, project report, project peer-review, and project presentations.

n  In the case of a group work, any act of plagiarism from any member of the group will result in ZERO mark for the entire group, unless such act has been reported by members of the group not involved in such act, in which case only the person(s) involved will receive ZERO mark.

n  In addition, any person involved in act of plagiarism may be subject to further investigation by the relevant University disciplinary units.
