Embedded system is a combination of hardware and software designed for a selected function. The systems are often programmable and fast functionality. It is a controller programmed by a real-time operating system (RTOS) with a dedicated function within an electrical system, often with real-time computing constraints. What is Embedded System? How Embedded System Works? Let’s find
Embedded systems are managed by microcontrollers or digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA), and circuit arrays. These processing systems are integrated with components dedicated to handling electric or mechanical interfacing. Embedded systems connect with surface of world through peripherals, linking input and output devices.
Single-functioned: An embedded system performs a specialized operation and does an equivalent repeatedly.
Tightly constrained: All compute systems have constraints on design metrics, but those on an embedded system are often especially tight. Design metrics may be a measure of an implementation’s features like its cost, size, power, and performance. It is a size to suit on one chip, perform fast enough to process data in real time and consume minimum power to increase battery life.
Reactive and Real time: Many embedded systems continually react to changes within the system’s environment and compute certain leads to real time. It continue to monitors and reacts to sensors. It must compute acceleration or de-accelerations repeatedly within a limited time; a delayed computation may result in failure to regulate.
Memory: It have a memory, i.e.; usually embeds in ROM. It doesn’t need any secondary memories within the computer.
Connected: Embedded system have connected peripherals to attach input and output devices.
HW-SW systems: Embedded system Software is employed for more features and adaptability. However hardware is used for performance and security.
The advantage of embedded systems to the system environment are the following:
Small size & specific: Embedded systems are specific to carry certain and unique functions, rather than a system which incorporates many functions, this means size and custom design will have the required components for them to function.
Reduced cost: Embedded systems user will be paying for a specific function that they desire, rather than many functions which are included, regardless if a user asks for them, this inevitable means cost are often reduced.
Portability: As first point mentioned size, however it also enclose another attribute which is advantageous, and i.e.; portability. Portable systems include mobile phones.
Low power operation: Many applications for example in medicine require energy saving appliances that can function for hours without having to plug them back into a power supply to recharge. This useful feature allows embedded systems to the reliable when functioning.
Real time response: Embedded systems are also called real time systems, where the response to external event has to be instant. Therefore, they are beneficial for applications i.e.; where the response to an external stimulus is critical.
As the embedded systems are dedicated to specific tasks, design engineers can optimize them to scale the dimensions and price of the merchandise. By increasing reliability and performance, some systems are mass-produced; this largely helps the economic area. We are technology-focused by these embedded systems.
