Digital Systems:  1st semester 2017  (Aug)

There are two parts in this class.  The first part is the basic building block of IT (teach by Prabhas 17 Aug - 28 Sept).  The second part is the asynchronous design (teach by Arthit).

my old lecture:  2015   2016

classroom :  Mon  10:00-11:00 Eng 4, floor 17, room 17-01 (xerox room), Thu 13:00-15:00 Eng 3 room 403


Today digital technology permeates every corner of our society. There are three big trends that shape our future. The first one is the coming of Artificial Intelligence.  The second one is the rise of Automation.  The last one the revolution of technology to transfer money.  These advancements rely on the power of computing.  To understand this future, we need a firm grip on how the technology work.  This class will discuss the basic of digital technology.  The idea of educating ourselves is not just read about the new development, but to "participate", or in the other words, to practice and experiment to see how things work. We will discuss the following topics:

Microprocessor  and how to program in assembly language
High level language and its translation into machine code
Interrupt and its role in multi-tasking
Low power programming
Concurrency, operating system and virtual memory
Multi-core processor

The highlight of the class will be a final project to really build a very simple processor from scratch.

How we learn

We learn by doing both hardware simulation and software.  The assignments will be given out periodically throughout the term. The final exam is "open book" and has an element of system design plus some "pseudo" programming.


Two parts (basic IT and asynchronous) each has 50 points (independently assess)

2-6 Oct 2017  midterm

Asynchronous design   (Aj Arthit lecture) 


1  Install Logicworks5.  Try some simple examples.
2  Learn how to write in Rz by reading  Quick Start Rz.  We use Rz version 3.6.

4B processor


S21 simulator and assembler  (latest update 24 Jan 2017)
Logicwork5  (tool for Logic Design, no installation required, just unzip)
I use Rz language as an example language.  See my Rz language homepage
Demonstrate the actual compiler of this course RZ.   Rz compiler on web
Compiler uses in this class  Rz 3.6  source and executable  (last update 13 Feb 2017)

Recommended free C compiler for Windows lcc-win32 . (for Windows 7, 8, 8.1 and 10).  Please also download and install "User Manual". You need it to look up the library function of this C.  (for OS X you need xcode, also free).
