An embedded system is a computer that has been developed to perform a single function. Alternatively, it is hardware that has been developed to do a particular function. The function of an embedded system is to provide the user with services, such as managing geniatech machinery or monitoring pressure and temperature measurements in commercial settings.
Below are some of the most common types of embedded systems:
Real-time embedded systems
Real-time systems are embedded systems that must meet time constraints and response specifications. A real-time system is any computer system that can perform all of its functions within a specific amount of time. Real-time systems are further subdivided into hard real-time systems and soft real-time systems. Soft real-time applications are those in which the system will only function correctly provided timing requirements are met. Applications requiring hard real-time systems are those in which the environment or people would be harmed or destroyed if timing constraints were not satisfied.
Standalone embedded systems
Embedded systems are single-purpose, stand-alone computers that cannot be used for other purposes. Because they are often small and compact enough to fit in a single box or container, they may be utilized in a range of applications. Since embedded systems generally employ microprocessors with limited memory and storage capacities, they are typically less expensive than other types of computing hardware. Most typically, freestanding embedded systems are utilized in the industrial control, telecommunications, medical, transportation, vending, and security sectors.
Networked Embedded Systems
In networked embedded systems, many processing units are linked via a network in order to perform an activity or provide a service. They could be used to monitor remote environmental sensors or to manage industrial activities such as mining operations. As they require high performance and dependability in a variety of areas, networked embedded systems employ separate processors for each function. Rather of industry-standard protocols such as TCP/IP (Transmission Control Protocol/Internet Protocol), they frequently employ proprietary protocols to connect across a network.
Mobile embedded systems
Mobile embedded systems are designed to do specific functions while being carried by a user throughout their daily activities. In order to transmit and receive data from distant locations, these systems usually employ cellular wireless technology. Probably the most well-known example of this type of embedded system is the mobile phone, which enables users to make calls from anywhere in the world without needing to be in close proximity to any other piece of technology other than the phone. Other examples include GPS devices for tracking freight shipments or locating lost pets, security cameras for monitoring people’s activities in public spaces such as malls and airports, and even medical devices such as pacemakers placed under the skin.
Based on the system’s power requirements, any type of embedded system is applicable. To choose the most suitable embedded system for your project, you must be familiar with all accessible types.
Depending on the use case, embedded systems are vital for numerous technologies, such as smart energy, vehicle (safety and comfort), biosafety, telecommunications, automation, etc. The difficulty in setting up of an embedded system will be determined by the number and type of processors utilised.
