Learn: Typical Features of Embedded Systems

Welcome!Welcome back! You've already learned about what embedded systems are. Today, we'll focus on their typical features and why they're used in various devices. Let's get started!

What are Embedded Systems?An embedded system is a computer system that is built into a larger device to perform specific tasks. It is designed to be efficient, reliable, and often works without user interaction. Examples include washing machines, traffic lights, and medical devices.

Key Features of Embedded SystemsEmbedded systems have unique characteristics that make them suitable for specific tasks. They are typically small, have low power usage, and are designed for reliability and efficiency. They run specialised software to complete their tasks.

Small SizeEmbedded systems are often small to fit into the device they control. For example, the embedded system in a microwave oven is compact and integrated into the control panel.

Low Power UsageMost embedded systems are designed to use minimal power. This is important for devices like wearable technology or medical implants that rely on battery power.

Specialised SoftwareEmbedded systems run software tailored to their specific task. For example, the software in a digital camera focuses on processing images and controlling the lens.

ReliabilityEmbedded systems are built to be reliable, as they often operate in critical environments. For example, the system in a pacemaker ensures consistent heartbeats for the patient.
