What is Meant by Embedded System?


An embedded system is a unique computer system that works inside a giant machine or system. Putting it together requires hardware and software because it has a specific function. Many everyday things, like cars, computers, home tools, energy management, medical equipment, and factory machines, have these kinds of systems.


You can depend on embedded systems because they're small, work in real-time, and don't use much power. Programmers make robots to perform specific tasks. These robots can interact with their environment using motors and sensors. They are also capable of working independently without assistance.


How Does an Embedded System Work?


Programmers program a set of instructions for embedded systems to handle hardware and perform tasks. The hardware comprises a microcontroller or microprocessor, memory, input/output ports, and occasionally other parts. When the embedded system is powered on, the firmware or software will connect to external devices or networks that are needed.


This process prepares the hardware for use. The embedded system collects sensor data, processes it, runs algorithms, and sends it to actuators or displays based on its programming.


It is essential to know how to program an embedded gadget. They use low-level languages like C and assembly to get the best speed and use of resources. Embedded systems can incorporate real-time operating systems (RTOS) to simplify job management, schedule setting, and resource allocation.


Components of an Embedded System


An embedded system needs certain vital parts to work. Microcontrollers and microprocessors are two examples. They're like the system's brains because of how they handle data and orders. RAM and ROM are two types of memory that store data and software instructions temporarily or permanently.


Using input/output interfaces, you can send control messages and exchange data with objects not connected to your computer. Sensors gather data about the world, and motors act on what the system tells them to do. Devices like Wi-Fi or Bluetooth can sometimes connect to other networks or systems outside. This makes it easier to send data and use remote controls.


Characteristics of Embedded System


Task-specific: Embedded systems operate within larger systems, performing specific tasks or functions designed to efficiently and accurately execute predetermined processes. Designed to meet the particular needs of their intended uses, they enhance speed and optimize resource utilization.


Time Frame Limit: Embedded systems work in real-time, meeting strict time limits to ensure actions and responses occur promptly. This property is critical in automotive systems, industrial automation, and medical gadgets.


Minimal UI: Embedded systems work on their own without needing user input, so they typically do not have a user interface. When users don't need to do much, you can use this design because it is easier, less complicated, and saves resources.


Power Efficiency: Power-efficient embedded systems try to do their jobs with as little power as possible while still being able to do them well. This function is necessary for battery-powered items, IoT devices, and other uses where power is essential.


Durability: The embedded Engineers ensure that integrated systems work well and last a long time. They can work well in rough places where the weather changes frequently and other issues arise. We extensively test them to ensure their strength and longevity, enabling their use in industrial, automobile, and aerospace settings.


Size: Embedded systems are small because they have a lot of hardware components and functions packed into a small space. Those who manufacture wearable technology, IoT sensors, or controllers for consumer gadgets should leverage this feature.


Device cost: When it comes to hardware and programming, embedded systems are a good choice because they save money and are fast. Manufacturers try to reduce costs for parts, production methods, and software development. This allows them to offer a variety of applications at affordable prices.

Classification of Embedded System? With Embedded Systems Examples


Stand Alone Embedded System


These systems perform specific jobs inside tools or other devices on their own. Household items like microwaves and smart TVs, as well as manufacturing robots, often use these systems. They operate without requiring an internet connection. Their independence allows them to function effectively without external influences, making them ideal for applications that do not require constant connectivity.


Examples- MP3 players, Microwave ovens, Calculator.


Real-time Embedded Systems


Applications that require immediate responses greatly benefit from these systems' careful construction to complete tasks within strict time limits. We can group these methods into two categories of embedded system:


Soft Real-Time Embedded Systems: While these systems try to complete jobs within set deadlines, they also allow for rare delays that don't have negative effects. Multimedia processing, home automation, and interactive systems utilize these systems for crucial but non-life-threatening reaction times.


Hard Real-Time Embedded Systems: These systems are time-bound, so they must finish jobs by the due dates. Many essential uses, such as space tracking, medical equipment that checks vital signs, and car safety systems, depend on their precise timing to function optimally and ensure public safety.


Examples- Traffic control system, Military usage in the defense sector, Medical usage in the health sector.


Network Embedded Systems


These systems can talk to other systems or devices, which makes it easier to share information and work together. Smart grids help people share energy easily, while control systems in industrial robotics ensure smooth operation of complex processes. Due to their ability to connect and collaborate, working in already linked places becomes easier. This improves automation and efficiency in all fields.


Examples- Home security systems, ATM machine, Card swipe machine.


Mobile Embedded Systems


These systems are portable and efficient, and they can power phones, computers, and innovative tech. They prioritize saving energy and keeping devices connected wirelessly. They also add features such as motion sensors, data sharing, and video to improve the user's experience. Because they are small and use little power, they work which is the best in mobile settings with limited resources.


Examples- MP3 player, Mobile phones, Digital Camera.


Classification Based on Performance and Microcontrollers


Small-Scale Embedded Systems


These devices don't have much memory or processing power because they use microcontrollers that can only do simple things. Many gadgets, appliances, and simple control systems use these microcontrollers. Microcontrollers are small, cheap, and use little power. They work well in places with limited computing power and where saving money is important.


Medium-Scale Embedded Systems


These systems use microcontrollers or microprocessors with a moderate amount of processing power and memory. They aim to find the right balance between speed and resource usage. They can perform more difficult tasks, such as processing data, linking sensors, and simple networking. Home electronics, industrial control systems, and car electronics that need a modest amount of computing power and connectivity often use medium-sized embedded systems.


Sophisticated Embedded Systems


Advanced microprocessors, known as microcontrollers, possess significant memory and operating power in these lightning-fast gadgets. It's easy for them to deal with complex algorithms, do many things simultaneously, process information in real-time, and connect to many devices and networks. Advanced embedded systems are used in robots, flight systems, communication gear, and medical devices.


These systems need high processing power to meet performance standards. High-tech embedded systems can innovate in highly demanding embedded computer settings, enabling scalability and flexibility.
