When multiple systems combine for a specific function is referred to as the Embedded system. The embedded system is a combination of software, hardware, and numerous parts that perform particular tasks. A system refers to a strategically laid out plan to ensure goal achievement within several steps.
What is Embedded System?
An embedded system is a microprocessor-based computer hardware system embedded in application (software) environments designed to perform a dedicated function (provide specialized support). Usually, an embedded system is a computer processor, computer memory, and input/output peripheral devices. Modern embedded systems consist of infrastructure or core network systems (for example, switches, bridges, routers, etc.) and end systems (for example, mobile phones and modems).
A standard desktop computer DOES NOT COME with an embedded operating system.
Can an embedded operating system be modified?
No, embedded operating systems can not be modified. However, you can easily convert your embedded system product to an IoT (internet of things) product. In that case, your embedded system can use an internet connection to start communication with other devices.
The next questions are embedded system examples.
Where Can You Find Embedded System Technology?
Embedded System Technology we can find in-network adapters for computing systems and mobile phones, industrial systems, car systems, control systems for air conditioning, surveillance systems, medical examples, robotics, etc.
Key characteristics of the embedded systems
- On the spot functioning within a time frame.
- Reliable and productive in the long run.
- It’s created around a real-time operating system.
- Very important for a specific function.
- It must be linked with peripherals for output and input.
- Interactive user interface.
- Adequate power consumption, low cost, and limited memory.
- No secondary memory for functioning.
Key Terminologies in Embedded Systems
Fault- Tolerance
The capacity of the computer systems to survive faults in the system is fault- tolerance.
Reliability
During the run time, the level of survival probability of the system is known as reliability.
Flexibility
The level of maintenance and manipulation a system can bear is the flexibility of the embedded system. For example, a device sent into space for collecting data breaks down accidentally or does not perform the specific function. The device must have an embed for the diagnosis of the problem in the machine.
Portability
The ease of incorporating embedded systems in different environments is portability.
Different types of Embedded Systems
- Sophisticated
- Medium
- Small
Sophisticated scale embedded systems
The sophisticated embedded systems have multiple hardware and software. A sophisticated embedded system has PLA’s, ASIPS, IPS, and various other components.
Medium-scale embedded systems
The system is designed with 16 or 32-bit microcontrollers. Source code engineering tools, C++, Java, and C, are used intensively in the embedded systems. These systems have both software and hardware complexities.
Small Scale Embedded Systems
An embedded system with an eight or 16-bit microcontroller is a small-scale embedded system. Cross assembler, IDE, editor, and battery are used for developing Small Scale Embedded Systems.
