Встраиваемое аппаратное обеспечение и операционные системы
- This course is intended for the 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.

- Module 1: Introduction to Embedded HardwareThis week will start from the basic information about Embedded Systems. Specifically, you will learn what are embedded systems and where they are applied as well as the main char-acteristics and challenges of embedded systems. You will discover how embedded systems communicate with the outer world.
- Module 2: Processing Elements of an Embedded SystemThis week we will go into details of what embedded systems consist of. Specifically you learn about the main blocks of any processing element of embedded systems. We will show you what embedded processors consists of and its main features. You will learn what reconfigurable architectures and FPGAs are, and what kind of ready-made platforms you can use to start work-ing with processing elements
- Module 3: Overview of operating systems and embedded operating systemsIn this week, we start with an overview of operating systems and embedded operating sys-tems for IoT. Primary functionalities of embedded operating systems are discussed. We learn how operating systems work: how memory is managed, how tasks are scheduled, what interrupts are and how they are 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 IoT are pre-sented. Concretely, after attending this week, you will able to explain why embedded systems often require an operating system describe how an embedded operating system works such as how memory is managed, how tasks are scheduled and how interrupts are handled. You will be able to differentiate between popular kernels for embedded operating systems. Differentiate be-tween popular embedded operating systems for IoT.
- Module 4: Contiki OS and Cooja simulationIn this week, we start to explore the Contiki Os in detail. First we discuss about the Conti-ki system and its kernel architecture. Furthermore, we explore how loadable programs are actu-ally implemented in Contiki. Second, we go through 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 communication stacks in Contiki. Next, prototheads are discussed to describe how application code is processed in Contiki. Furthermore, APIs of multi-threading is discussed. Last but not least, the 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 applications are presented in detailed via an example application. Concretely, after at-tending this week, you will able to describe how Contiki system and its kernel architecture are built. Distinguish Contiki services and libraries in terms of how they are built, when they are invoked and why they are used. Describe how communication is implemented and supported in Contiki and what protocols Contiki can support. Explore how application's code is processed in Contiki and important functions of API for multithreading in Contiki use Cooja for simulating wireless sensor networks applications.
