The content of the course is a mixed between hardware and software.
Embedded systems are computer systems with special requirement on
constraints such as low power, high integration, real-time. This course
explores Embedded systems design. On the hardware side, it includes embedded
processors and low level programming, logic design, integrated
circuits. On the software side, it includes Operating systems
scheduling and real-time constraints. Here are the list of topics:
Introduction to embedded and real-time systems
Assembly level programming
Memory, Peripherals and Microprocessor interface
Operating systems and task scheduling
Real-time systems and their requirements
Internet of Things
How we learn
We learn by doing both hardware and software. The activities include
embedded system model construction, some programming, and hands-on session.
The assignments will be given out periodically throughout the term. A small
project will be given around midterm. Students must present the results of
their projects. At the second half of the semester, a real hardware
will be presented. Students are assigned to design and implement a
small embedded system. The project will be presented in the class. The
final exam is "open book" and has an element of system design plus some
old lecture 2017

final project presentation
1) Write a program for IoT board to function as Frequency meter.
Reading input from Analog port (10) and calculate the period between
"crossing zero" of the wave. Using that information to compute the
frequency. Please email your solution to my email
firstname.lastname@example.org using the title prefix with embed: .
2) Study the output assembly language generated from Rz input
source program. Investigate how a function calls another
function. How a parameter is passed.
3) 11 Feb 2018 -- Play with mos2.txt, try to make it to work
(by modify the simulator or mos2.txt itself).

Mid term projects
Invent a demo program that uses two IoT boards (I will provide a special
edition IoT simulator). These boards will have extra two ports (for
writing/reading one integer) for communication. Each board can run a
single program or multi-task (by using MOS). You should try to show
an interesting demo.
