What is an embedded system?
An embedded system is a method of functioning, organizing, and carrying out single or many tasks that follows a set of rules. All the units in an embedded system assemble and work together by the software. An Embedded system is a specialized electronic device coupled with computer hardware. Depending upon the application requirements, the system may be programmed or non-programmed. Different components of an embedded system are used while building a plan. Join the Embedded System Courses in Chennai and gain first-hand knowledge through experienced industry professionals.
The requirements for an embedded system are gradually increasing in the modern world. All the complicated functions are simplified because of the embedded system. Embedded system integrated with multiple products like washing machines, cameras, automobiles etc.,
In this section, the Components of the Embedded System are listed below:
Power supply
In an embedded system, the power source is the core of the embedded system. Generally, the system consumes 5V. Depending upon the requirement, power ranges vary from 1.8V to 3.3V. The source of power is distributed through a battery or wall adapter. A constant power supply needs for an embedded system to do a specified task. Dissipation should be allowed, and the power supply should be as efficient as feasible.
Processor
The processor works as the central processing unit of the embedded system. The role of the processor in the plan is to decide the performance. Various processors are available in the market. As per the requirement, the processor can be selected. An embedded system can work as both a microprocessor and a microcontroller. Generally, the system uses 16 32-bit processors. The processor should be high-performance and have fast functions. Embedded Systems Training in Chennai teaches about all types of processors used in embedded systems.
Memory
The core of the embedded system is the memory unit. Various controllers are used in embedded systems. The memory is also mounted with microcontrollers. Generally, two memory variants are used one is RAM, another one is ROM. In RAM, data will be stored for a short period. When the system shuts down, data will be deleted. ROM is used for saving the software program permanently.
Communication ports
there are different communication ports used in embedded systems, and ports are a kind of interface to communicate with other systems. Some of the ports are UART, RS-485, Ethernet Etc.
Circuits
Various hardware components can be employed for design purposes while creating an embedded system. The embedded system’s application entirely determines the chosen circuit. A specific set of functions are stored in the circuit to do a specified task.
Conclusion:
These are the main components of an embedded system. And other hardware components of the embedded system will be discussed in upcoming articles. Get more knowledge about microprocessors and microcontrollers from the Embedded Course in Coimbatore.
