Prevailing in the Technological World: Different Types of Embedded Systems
The essence of today’s tech-driven world, embedded systems, deeply interweaves with the advanced devices we use on a regular basis, undertaking dedicated functions and enhancing our overall convenience. This comprehensive review offers a detailed insight into the varied types of embedded systems.
Defining Embedded Systems
Conceptualized as a computer hardware setup integrated with distinct software, an embedded system is tasked to execute a specific activity within a broader structure. Their prevalence spans from mundane objects such as digital watches or microwaves, to high-end devices like MRI scanners.
Types of Embedded Systems: A Categorization
For a clearer grasp of the broad field of embedded systems, a thorough classification is indispensable. The bifurcation of embedded systems generally revolves around their performance and functional prerequisites.
Classification Based on Performance and Functional Requirements
Primarily, they are divided into three segments, each characterized by unique features:
1. Real-Time Embedded Systems
Real-time embedded systems are expertly created to accomplish a task within a defined time constraint, further divided into two sub-classes:
a. Hard Real-Time Systems: Operate tasks where any delay could bear substantial repercussions, such as missile systems or vehicle’s airbag controls.
b. Soft Real-Time Systems: These also work under a time limitation, but a delay, though undesirable, does not trigger grave effects.
2. Stand-Alone Embedded Systems
The self-dependent stand-alone embedded systems can operate independently, examples include digital cameras, MP3 players and video game consoles.
3. Networked Embedded Systems
Systems such as intrusion detection and home security, form part of the networked embedded systems that perform the specified function in correlation with a network.
Classification of Embedded Systems Based on Microcontroller Use
Microcontroller usage also contributes to the classification of embedded systems, forming three categories:
1. Small Scale Embedded Systems
With an 8 or 16-bit microcontroller and limited hardware and software features, these systems correspond to simpler tasks.
2. Medium Scale Embedded Systems
Having 16 or 32-bit microcontrollers, these systems encompass increased software and hardware complexity including aspects like scalability, firmware, and real-time data processing.
3. Sophisticated Embedded Systems
For multifaceted applications employing intricate hardware and software systems running complex algorithms, sophisticated embedded systems like multi-core processing systems find optimal use.
Applications of Embedded Systems
Reflecting upon their classifications, the applications of embedded systems display immense extent and variety across industries.
1. Automotive Industry
Intelligent transport, adaptive cruise management systems, and airbag controllers are a few instances of automotive applications of embedded systems.
2. Healthcare field
Embedded systems are essential in physiological monitors, digital stethoscopes, as well as surgical robots within the medical field.
3. Consumer Electronics
Consumer goods like mobile devices, printers, modems, gaming consoles, and digital cameras are replete with embedded systems.
Operating silently behind various endeavours, embedded systems form the backbone of many technologies we utilise today. The diverse amalgamation of the different types of embedded systems and their varied applications offer an in-depth understanding of this technological spectrum.
