Languages for Embedded System Design
CVN Summer 2003
Embedded systems are single-purpose computers that are often part of
larger systems such as cars or telephones. Their design requires
tight integration of application-specific hardware and software, and often
have strong constraints on power, cost, and speed. While most
embedded systems are currently designed using ad hoc techniques, the
complexity of future systems will demand formal design techniques.
The course is an introduction to a wide variety of languages used to specify embedded systems. Embodied in these languages are different models of computation, such as sequential, dataflow, discrete-event, and synchronous, that shape how design problems may be solved. Knowing about more of these languages will give you a bigger bag of tricks for solving design problems.
When you have completed the course, you will have gained some experience using each of the languages, will have learned about how each of them are implemented, and will have completed a project that will give you more in-depth knowledge of one of the languages, either by using it to design a system or by creating an analysis tool for the language.

This is a course about both hardware and software languages, so I expect you to be familar with programming in a language such as C or Java, be aware of language and compiler design issues and also be somewhat familiar with digital logic design. A simple litmus test: you should be able to write a program that performs a depth-first traversal of a graph, know what an abstract syntax tree is, and should be able to design a four-bit binary counter using NAND gates and flip-flops.

Near Columbia, this is available at Papyrus Booksellers, at the corner of 114th and Broadway. Textbooks are downstairs.
The main point of this class is a large language-related
project. I envision two types of project:
The outcome of your project will be a workshop-class
paper, meaning it should be scholarly, accurate, and brief, but it
does not have to be polished. Ideally, it should be in a form
suitable for submission, but actually submitting it to a workshop or
conference is not required.
Like all academic papers, the contents of the writeup should be your own and appropriate credit (i.e., citations) given where you have used or adapted other's work.
|Project Report Format|
Make your project report look like a conference paper:

Out of 100 points for the literature survey, 50 are specific to it:
|Sample Project Proposal|
|I will implement a library supporting Kahn Process Networks in Java. It will employ the scheduling algorithm due to Parks and have facilities for detecting a deadlock condition. I will construct the library and test it first on the small example from the book, then look for more examples, perhaps the video decode example described by Vissers. Although the final goal of this project will be functional correctness rather than efficiency, I plan to measure the scheduling/context switching overhead by statistically sampling the Java process.|
50 % Project
15 % Midterm 1
15 % Final
20 % Homework
You are permitted to collaborate on homeworks,
however, the homework you submit must be your own unique creation, and you
must understand and be able to explain your result. My intention is
not to reduce your workload, but to give you the opportunity to learn
from your peers. See Columbia academic policies
for more details.
Collaboration on the project is mandatory unless your "team" is just you.
Collaboration on the midterms is forbidden.
|Late Policy||Zero credit for anything handed in after the due date without explicit approval of the instructor. Homeworks are due at the beginning of class on the designated due date.|
|A sample LaTeX file, a BibTeX file, a Makefile, and the PDF file they all produce, illustrating how to write a paper in LaTeX. You may use this as a template for the literature survey and final project report. Its content is also representative of what I am looking for in a final report.|
