Designing and Developing Embedded Systems

Introduction

An embedded system is a dedicated machine that achieves specific functions as opposed to a general-purpose machine that can function many tasks. The reason it's called an embedded system is that the processing unit is embedded or hidden within the product. For example, a washing machine functions to clean clothes, but embedded within is a network of controllers and processing units to ensure proper washing cycles. 

Topics:

Micro-controller 

Operating System 

Secure Boot 

Realtime Processing 

Overview of these topics

• Microcontrollers are the brains of embedded systems. They control the hardware and software of the system and ensure that it functions properly.

• Operating systems are essential for managing the resources of embedded systems. They ensure that tasks are executed efficiently and that the system is protected from malware attacks.

• Secure boot: the mechanisms for securely booting a system, ensuring that only authorized software runs on the device.

• Realtime processing is essential for many embedded systems. It ensures that tasks are executed within a specified time period, which is critical for applications such as air traffic control and medical devices.

Summary

This primer has introduced the basics of embedded systems. We have discussed the role of microcontrollers, operating systems, secure boot, and realtime processing in embedded systems. These topics are essential for understanding how embedded systems work and how to design and develop them.
