Embedded Systems

Embedded Systems

1. Is a computing system designed to perform one or a few dedicated functions, often in a real-time computing system

   • - Phones - Smart Cameras - Video Cameras - Calculators - Home appliances - Home Security System - Automotive System
   • General Aspects of Embedded Systems
     • 1. Variety of interfaces that allow the system to measure, manipulate, and otherwise interact with the external environment.
       • 2. Software often has a fixed funtion and is specific to the application
         • 3. It has to be efficient and with low energy consumption

2. The Internet of Things

   • Is a system of interrelated computing devices, mechanical and digital machines, objects, animals, or people that have unique identifiers and the ability to transfer data over a network, without requiring human-to-human interactions
     • Generations of the loT
       • 1. Information Technology (TI) 2. Operation Technology (OT) 3. Personal Technology 4. Sensor/actuator technology

3. Embedded Operating Systems

   • - Windows - Linux - Mac

4. App Processors versus Dedicated Processors

   • Application processors are defined by processors ability to execute complex operating systems (Android and Chrome)
   • Most embedded systems employ a dedicated processor (Specific taks required)

5. Microprocessors vs Microcontrollers

   • Microprocessor chips included registers (instruction processing logic)
   • A microcontroller chip makes a substantially different use the logic space available

6. Embedded vs Deeply Embedded Systems

   • A subset of embedded systems, and a quite numerous subset, is referred to as deeply embeded sustems
