Importance of Embedded Systems in Our Daily Life
An embedded system is basically a computerized or processing system that is used as an embedded part of any large complete machine, device, mechanical, electrical, or electronic system and it controls the operation of that machine or system. A complete embedded system is built with input devices, output devices, processors, memory, etc. You will see the modern embedded system is built with microprocessors, controllers, etc. The embedded system is embedded with a system to control the physical operation of that system electronically. Nowadays embedded system is used from small portable compact devices to a large industrial system. You can see the application of embedded systems everywhere from home appliances to consumer electronics, industrial appliances, medical, telecommunication, military, etc.
Embedded systems are mostly designed to perform a specific task such as it takes a constant input and process and provides a constant output. Generally, in most of the cases, the embedded system does not have any user interface. Sometimes it has only normal buttons, LEDs, etc.
A brief description of Embedded System
The main parts of an embedded system are sensors, converters, processors, memory, actuators, etc. A sensor is a device that senses the physical changes and generates the signal that is to be given as an input signal of the system. A sensor or transducer generally generates the signal in analog form but the processor is capable to process only the digital signals. So here an analog to digital converter is required that will take the analog signal from the sensor or transducer and then convert it into a digital signal. This digital signal will be fed to the processor for processing.
The processor will process the signal and it uses memory to store the data or information for temporary during the program execution or permanently for future processing. The processor takes inputs from the ADC, Memory, and manual input devices such as any keypad or feedback circuit.
The processor also generates the signal in digital form. But some of the output devices of the embedded system such as actuators are work with analog signals. So here a digital to analog converter is used to convert the digital signal generated by the processor into an analog signal that will be used to operate the actuator.
Sometimes driver circuits are used to increase the strength of the signal. Embedded systems can be connected to other systems or store programs with different peripherals such as USB(Universal Serial Bus), Serial Communication Interface(SCI) such as RS - 232, RS - 485, RS - 422, etc. Modern embedded system uses both wire and wireless technology.
