Embedded Systems:
An embedded system is a programmed controlling and operating system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts.
Embedded Systems Are classified into three types based on the performance of microcontroller they are Small Scall, Medium Scale, Large Scale Embedded Systems.
Small Scale Embedded Systems:
These types of embedded systems are designed with a single 8 or 16-bit microcontroller, that may even be activated by a battery. For developing embedded software for small-scale embedded systems, the main programming tools are an editor, assembler, cross assembler and integrated development environment (IDE).
Examples: Washing Machines, Security Alarms.
Medium Scale Embedded Systems:
These types of embedded systems design with a single or 16 or 32-bit microcontroller, RISCs or DSPs. These types of embedded systems have both hardware and software complexities. For developing embedded software for medium scale embedded systems, the main programming tools are C, C++, JAVA, Visual C++, RTOS, debugger, source code engineering tool, simulator, and IDE.
Examples: telecommunication, home Auto machine.
Large Scale Embedded Systems
These types of embedded systems have enormous hardware and software complexities, that may need ASIPs, IPs, PLAs, scalable or configurable processors. They are used for cutting-edge applications that need hardware and software Co-design and components which must assemble in the final system.
Examples: Set-top Boxes, Robotics.
I hope this article was successful in explaining you the basic classification of Embedded Systems.
