Components of the Embedded System

What are Embedded systems?

Embedded systems are used to manage a certain operation inside of a device. Embedded systems are often merely made to carry out this task repeatedly, but more advanced ones can take control of whole operating systems

 In our daily lives how important are embedded systems?

The significance of embedded systems in daily life is frequently contested. These tiny computers have a significant impact on how we commute, spend our free time, do business, and carry out many other daily duties since they are incorporated into numerous systems to carry out specialized image and data processing functions.

 Components  

• Processor

• Timers counters

• Circuits used in application

• Power supply

• Communication ports

• Memory

• Output and Input

 Processor

• The processor is the system's brain in any embedded device.

• The processor makes decisions about the embedded system's performance.

• Many different types of processors are offered on the market and can be chosen based on user needs

• Microcontroller and processor functions can be performed by the embedded system

Timers counters

• There is frequently a requirement for the application to include a delay

• For instance, a delay is needed in LED display applications so that the LED can continue to blink.

• And the embedded system can make use of a timer and a counter for that.

• Programming can be done in a way that causes the embedded system to generate delays

Circuits used in application

• Several hardware components can be employed for design purposes when the embedded system is created

• The embedded system's application dictates the circuit choice in full.

Power supply

• To power the embedded system circuit, the power supply is a crucial component.

• Typically, an embedded system needs a 5 V supply, though it can also be between 1.8 and 3.3 V.

• A wall adaptor or a battery can be used as the power source

• The power supply is chosen based on the needs of the application and the user. 

Communication ports

• When communicating with different kinds of embedded systems, the communication port is the type of interface that is utilized.

• Numerous communication port types, including UART, USB, Ethernet, RS-485, and others, are available in embedded systems.

Memory

• The embedded system uses a variety of microcontrollers, thus each one has its built-in memory.

• RAM (random access memory) and ROM are the two main types of memory (Read-only memory)

• Since RAM is a volatile sort of memory, data saved there momentarily is lost when the system is turned off\

Output and Input

• The input is required to communicate with the embedded system when it is in use. 

• Both the user and the sensor can offer input to the embedded system. Devices can only be linked to the designated ports on the embedded system due to the fixed input and output ports. 

• P0, P1, P2, and several others are examples.

Conclusion

Embedded systems are also quickly evolving into a change agent in the computer, data communications, telecommunications, industrial control, and entertainment industries. Any field where automatic systems are used will be beneficial and save both individuals and groups of people.
