Embedded Hardware and Operating Systems (Coursera)

This course is intended for the Bachelor and Master’s students, who like practical programming and making IoTs applications! In this course we will talk about two components of a cyber physical system, namely hardware and operating systems.

After completing this course, you will have the knowledge of both hardware components and operating systems. You are able to plan and use embedded operating systems in resource-constraint devices for Internet-of-Things (cyber physical system) applications. In addition, you can use Cooja simulation for designing and simulating wireless sensor network applications.

We have 4 modules, each with a graded quiz in the end and finally we have one peer reviewed programming assignment.

The course is actually quite fun at the end when you are playing around with Cooja simulation for IoTs applications. So you can create and simulate your own design for sensor network applications. A lot of features and examples of Contiki and Cooja can be explored via assignments. There are some optional assignments of wireless sensor network applications for students who want to explore more about embedded OS in IoTs applications.

Who is this class for: This course is intended for the Bachelor and Master’s students, who likes practical programming and making IoTs applications!

Syllabus:

WEEK 1

Introduction to Embedded Hardware

This week will start from the basic information about Embedded Systems. Specifically you will learn (1) what are Embedded Systems and where they are applied as well as (2) the main characteristics and challenges of Embedded Systems. (3)You will discover how Embedded Systems communicate with the outer world.

Graded: Introduction to Embedded HW (Graded quiz)

WEEK 2

Processing Elements of an Embedded System

This week we will go into details of what Embedded Systems consist of. Specifically you learn about the main blocks of any Embedded System Processing Elements. We will show you what (1)Embedded Processor consists of, its main features. You will learn what (3)reconfigurable architectures and FPGAs are what kind of (4) ready made platforms you can use to start working with Processing Elements.

Graded: Processing elements (Graded quiz)

WEEK 3

Overview of operating systems and embedded operating systems

In this week, we start to have an overview of operating systems and embedded operating systems for IoTs. Primary functionalities of embedded operating systems are discussed. We learn how operating systems works such as how memory is managed, how tasks are scheduled, what is interrupt and how it is handled. After this, we deepen our learning with the popular kernels for general and embedded operating systems. Linux (monolithic) kernel, micro kernel and modular kernel are presented. In addition, several popular embedded operating systems for IoTs are presented. Concretely, after attending this week, you will able to (1) explain why systems especially embedded systems require an operating system (2) describe how an embedded operating system works such as how memory is managed, how tasks are scheduled and how interrupts are handled. (3) differentiate popular kernels for embedded operating systems. (4) Differentiate popular embedded operating systems for IoTs.

WEEK 4

Contiki OS and Cooja simulation

In this week, we start to explore Contiki Os in detailed. First we discuss about Contiki system and its kernel architecture. Furthermore, we explore how loadable programs are actually implemented in Contiki system. Second, we go thourgh services and libraries in Contiki to see how they are built and when they can be invoked. Third, we discuss communication in Contiki via details of uIp and Rime commnunication stacks in Contiki. Next, prototheads is discussed to describe how application’s code is processed in Contiki. Furtheremore, API of multithreading is discussed. Last b ut not least, Cooja simulator – a simulator for wireless sensor networks based on Contiki is introduced. All steps of installing and applying Cooja for a wireless sensor network application are presented in detailed via an example application. Concretely, after attending this week, you will able to (1) describe how Contiki system and its kernel architecture are built. (2) distinguish Contiki services and libraries in terms of how they are built, when they are invoked and why they are used. (3) describe how communication is implemented and supported in Contiki and what protocols Contiki can support. (4) explore how application’s code is processed in Contiki and important functions of API for multithreading in Contiki (5) use Cooja for simulating wireless sensor networks applications.
