UCR EE/CS120B: Introduction to Embedded Systems

UCR EE/CS120B: Introduction to Embedded Systems, Spring 2002

Overview

This course deals with the exciting field of designing embedded computing systems -- those computers hidden in all sorts of electronic devices, like digital cameras, MP3 players, video games, automobiles, fax machines, copy machines, printers, pacemakers, hearding aids, hospital equipment, and so on. It introduces the student using a unified view of hardware and software design -- mapping desired functionality to a collection of single-purpose processors (digital hardware and peripherals) and general-purpose processors (microprocessors). Students will gain experience building real digital systems using VHDL, synthesis and FPGAs (Xilinx), and programming embedded microprocessors (Intel 8051 8-bit microcontroller).

Hardware/software tradeoffs

Notes

Lecture and lab material overlap, but are quite independent, with lectures dealing with general principles, and lab dealing with specific software and hardware. Lecture exams will focus on lecture material, but may include some amount of lab material. Students in lab will work with a partner. Lab exams may be held during the quarter to ensure each individual is learning (i.e., not relying too heavily on one's partner).

Important note on academic dishonesty: cheating will be punished severely. For those who don't want others' cheating to cheapen your own hard work and hurt your grade -- there is an anonymous cheating reporting form at: https://www.cs.ucr.edu/cheating/. While students may discuss material generally (and this is encouraged!), HOMEWORK SUBMISSIONS MUST REPRESENT INDEPENDENT WORK .

Submitted homeworks should be neat and legible -- sloppy or unnecessarily long homework submissions may lose points or may not be graded. You probably want to do a draft of the homework, and then create a neater copy to turn in.

Regrade policy: corrections to graded material must be submitted within one week of the distribution of the graded items. Corrections to grades database entries must also be corrected within one week of the grades being posted.

Email address: In lab, you'll be asked to provide us with a UCR email address. Some announcements, and your scores during the quarter, will be sent to that email address. If you commonly read email from another address (e.g., yahoo or hotmail), then you must still provide us with your UCR address, but you might then create a .forward file in your UCR account for your more common address.

Lab guidelines

You should plan to stay for the duration of your 4-hour scheduled lab time. If you finish a lab before a due date, you should proceed to work on the next lab if it is available, or develop additional designs related to the course.
Each lab assignment's grade will typically consist 10 points: 3 points for your lab demo (simulation and board), 4 points for your code and/or schematic (must be well organized and commented), and 3 points for your lab report.
Lab reports are due within 24 hours from the end of the scheduled lab time on the date you are checked off for your demo. Use the report form (in text format, not Word, please). Late lab reports will lose points.
Lab reports, code and results (preferably zipped) should be e-mailed to the TA of your lab.
The TA's may not be available for help 15 minutes before the end of each lab. This time is reserved for checking out completed labs.
You will be working in groups of two. You are welcome to choose your own lab partner. Groups of three will not be allowed.
The TA's will check out the Xilinx boards and other equipment to each group when required. Boards are only available during scheduled lab. Student must check the boards back in when done, and must be sure to sign the check in sheet. Students should also be sure the TA records the score of your lab demo.
The Xilinx boards are pre-wired. Please do not change any wiring unless specifically instructed by the TA. Students may be held responsible for boards damaged due to misuse.
You are required to go to the lab section you are registered in. If you wish to change your lab section, this must be pre-approved by the TA.
The key to a successful and enjoyable lab experience is to prepare extensively before coming to lab. Xilinx software comes with the Wakerly book, and VHDL simulation software can be purchased inexpensively. You should code most of your VHDL and C before coming to lab. Lab time is for testing things out and experimenting.
Suggestions to help us improve the lab are very welcome.

Key Resources

We recommend that students interested in the digital systems field purchase the following:
Aldec VHDL simulator student edition
It's an easy to use yet powerful VHDL simulator written for Windows, and I think a great deal (around $50).
Online "VHDL-by-Example" tutorial (from UCR).
