What do you understand by embedded system design?

An embedded system is a microprocessor-based computer hardware system with software that is designed to perform a dedicated function, either as an independent system or as a part of a large system. At the core is an integrated circuit designed to carry out computation for real-time operations.

Embedded systems design is the process where hardware and firmware designers come together to build embedded systems from scratch. This involves PCB design, where the necessary components are connected to build functional circuits.

Figure1 shows the steps in the design process. They are requirements gathering, specification formulation, architecture design, building of components, and system integration.

Embedded systems must be designed across multiple levels of abstraction: system architecture; hardware and software systems; hardware and software components.

Embedded systems are classified into four categories based on their performance and functional requirements:

• Stand alone embedded systems.
• Real time embedded systems.
• Networked embedded systems.
• Mobile embedded systems.

An ATM is an embedded system which utilizes a crowded computer to set up a network between a bank computer and an ATM itself. It also has a microcontroller to bear both input and output operations.

The embedded systems basics include the components of embedded system hardware, embedded system types and several characteristics….Usually, an embedded system consists of:

• Power Supply.
• Processor.
• Memory.
• Timers.
• Serial communication ports.
• Output/Output circuits.
• System application specific circuits.

The overall goal of electronic embedded system design is to balance production costs with development time and cost in view of. Today, IC technology offers the possibility of integrating so many functions onto a single chip that it is indeed possible to implement an “environment-to-environment” system on a single chip.

Examples of embedded systems include:

• central heating systems.
• engine management systems in vehicles.
• domestic appliances, such as dishwashers, TVs and digital phones.
• digital watches.
• electronic calculators.
• GPS systems.
• fitness trackers.

Applications of Embedded Systems:

• Motor and cruise control system.
• Body or Engine safety.
• Entertainment and multimedia in car.
• E-Com and Mobile access.
• Robotics in assembly line.
• Wireless communication.
• Mobile computing and networking.

What is an embedded system? A simple definition would be, an embedded system is a “special purpose computer” purpose-built to serve a specific purpose. For example, a calculator is a special-purpose computer as compared to a PC.
