Oct 5, 2024 · An Embedded System is a compact computer incorporated into a more extensive system, device, or machine. Its primary function is to control the device and promote user interaction. Typically, these systems are designed to fulfil one or more tasks. Embedded devices are not usually user-programmable; the manufacturer pre-installed their software.
An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system.

An embedded systemis a microprocessor-based computer hardware system – a combination of a computer processor, storage medium (eg: RAM) and input/output peripheral devices – which form part of an independent or larger mechanical or electrical system, device or machine. Within these products, an embedded system contains sequentially executed software...
Embedded systems work by combining hardware and software components to perform specific tasks within a larger system. Here’s a simplified explanation of how embedded systems typically function: 1. Input: Embedded systems receive input from the surrounding environment through sensors, buttons, switches, or other input devices. These inputs can inclu...
Sensor
In an embedded system, a sensor is a component or device that detects and measures physical quantities or environmental conditions. It converts these physical inputs into electrical signals or digital data that can be processed by the embedded system’s microcontroller or microprocessor. Sensors play a crucial role in providing input to the embedded system, enabling it to interact with and respond to its surrounding environment. There are various types of sensors used in embedded systems, each...
A-D Converter
An A-D converter, also known as an analog-to-digital converter, is a vital component in embedded systems that is responsible for converting analog signals into digital data. In an embedded system, an A-D converter enables the system to interface with and process analog input signals from various sensors, transducers, or other analog devices. Analog signals are continuous and represent real-world phenomena such as temperature, pressure, voltage, or sound. However, most embedded systems process...
Processor & ASICs
Processors & ASICs process the data measured by the sensor to assess the output. Processors and ASICs (Application-Specific Integrated Circuits) are two types of key components used in embedded systems. Component 1 – Processors: Processors, also known as microprocessors or central processing units (CPUs), are the brains of an embedded system. They handle the computational tasks and execute the instructions necessary for the system’s operation. Processors are responsible for processing data, p...

There are various different types of embedded systems all dedicated to performing specific and dedicated tasks combining together both hardware and software. They can be classified into different types based on performance and functional requirements.
Simple Control Loop: The software simply operates on a loop.Interrupt-Controlled System: Tasks are triggered by events like a preset timer.Cooperative Multitasking: The software operates similarly to a simple control loop, but the loop is hidden in an API.Preemptive Multitasking: Low level code switches between tasks based on a timer connected to an interrupt.The first recognised embedded system was developed in the early 1960s by Charles Stark Draper at the MIT Instrumentation Library, the Apollo Guidance Computer used monolithic integrated circuits to reduce its size and weight and it was used by astronauts to collect real-time flight data – which was a progression from the first programmable computer...
