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.
An embedded system is a microprocessor-based computer hardware system embedded in application (software) environments that are designed to perform a dedicated function (provide specialized support). The Embedded system consists of infrastructure or core network systems (for example switches, bridges, and routers, etc.) and end systems (for example mobile phones and modems).
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
The capacity of the computer systems to survive faults in the system is fault- tolerance.
During the run time, the level of survival probability of the system is known as reliability.
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 diagnosis of the problem in the machine.
The ease of incorporating embedded systems in different environments is portability.
Different types of Embedded Systems
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 tool, 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.
