There are some obvious differences between single chip microcomputer and embedded system, mainly in definition, function, application scenario and complexity.
Definition: SingleChipMicrocomputer, also known as microcontroller or system on chip (SoC), is a microcomputer system integrated on a single chip. It contains basic components, such as central processing unit (CPU), memory and input/output (I/O) interface, which are used to perform specific control tasks.
Embedded system refers to a special computer system that integrates computer hardware, software and external devices. It is usually used to perform specific control or monitoring tasks, and embedded in various devices or systems, such as household appliances, automobiles, industrial equipment and so on.
Functions and characteristics: Single chip microcomputer has the advantages of small size, low power consumption and low price, and is suitable for various control occasions. Its function is relatively simple, and it is usually used to execute some simple control logic.
Embedded system has more powerful functions and flexibility. It can be customized according to different application requirements, and can realize complex control algorithms, data processing, network communication and other functions.
Application scenario: Single chip microcomputer is widely used in various small control systems, such as smart meters, smart homes, toys and so on.
Embedded system is widely used in various large-scale equipment and systems, such as automobile control system, medical equipment, industrial automation and so on.
Complexity: In contrast, the structure and function of single chip microcomputer are relatively simple, and usually do not need the support of complex operating system.
Embedded system may involve more complex hardware and software design, including real-time operating system, multitasking and network communication.
Generally speaking, there are obvious differences between single chip microcomputer and embedded system in definition, function, application scenario and complexity. The choice of which technology to use mainly depends on the specific application requirements and scenarios. In simple control tasks, single chip microcomputer may be a more economical and practical choice; However, in applications that need to realize complex functions and high customization, embedded systems may be more suitable.
