Sincerely solve what is the relationship between embedded and single chip microcomputer Be detailed

IEEE (Institute of Electrical and Electronics Engineers) definition of an embedded system: "a device used to control, monitor, or assist in the operation of machinery and equipment". The original text is:

devices used to control，monitor or assist the operation of equipment，machinery or plants）。

An embedded system is a specialized computer system that is part of a device or device. Typically, an embedded system is an embedded processor control board where control programs are stored in a ROM. In fact, all devices with digital interfaces, such as watches, microwave ovens, video recorders, cars, etc., use embedded systems, some of which also contain operating systems, but most embedded systems are implemented by a single program to implement the entire control logic.

As can be seen from the diagram on the right, an embedded system is a combination of software and hardware, and can also include accessories such as machinery.

The definition of embedded system generally recognized in China is: application-centered, computer technology-based, software and hardware can be tailored, to adapt to the application system for function, reliability, cost, volume, power consumption and other strict requirements of the computer system.

The microcontroller is only a computer at the embedded hardware layer, and of course it is one of the cores of the embedded system.

Embedded advanced, MCUs can only be used for small projects.

A single-chip microcomputer, of course, can be understood as "an integrated circuit chip".

But in the early days,"Intelligent circuit system with single-chip microcomputer as the core".Also abbreviated"MCU".

Later, in order to appearTallSome, just put it"MCU system".Renamed again"Embedded".now

Therefore, embedded and single-chip microcomputer can also be said to be the same, but they are just the names of the early and late periods.

Hello dear, glad to answer for you. Pro: What is an embedded system? How does it relate to microcontrollers.

An embedded system is "a specialized computer system designed for a specific application that is completely embedded in a controlled device." It is closely related to the single-chip microcomputer, it can be said that everything single-chip microcomputer as a controller product is an embedded system, of course, the embedded system is not only the application of the single-chip microcomputer, but also includes the application system of advanced processors such as ARM and DSP. ”

What is an embedded system? How does it relate to microcontrollers.

Microcontroller is one of many embedded processors, and the current general understanding is that embedded mainly refers to processors such as ARM DSP. An embedded system is a collection of hardware and software that implements a circuit that achieves a certain function.

The connection between the single-chip microcomputer and AutoCAD is not very large, because the single-chip microcomputer is a micro-control chip used in the control field, and AutoCAD is an application design software used in the mechanical or construction industry. There is no necessary connection between the two, but if you want to engage in single-chip microcomputer, because you need to design the circuit peripheral control diagram, in addition to using Protel99SE software when designing the circuit schematic, you may need AutoCAD software to assist in the design of your peripheral wiring diagram. Maybe you've encountered these kinds of problems when looking for a job.

The difference between embedded and microcontroller.

The difference between single-chip microcomputer and embedded in the system composition structure:

1) The basic structure of single-chip microcomputer.

A microcontroller consists of a combinator, a controller, a memory, and an input and output device.

2) Embedded system components:

Embedded systems generally consist of embedded microprocessors, peripheral hardware devices, embedded operating systems, and specific applications.

The first step of embedded system design is to determine the main control components of the system based on the specific application, comprehensively consider the requirements of the system for cost, performance, scalability, development cycle and other aspects, and build the system hardware platform with it as the core.

The difference between single-chip microcomputer and embedded hardware composition:

A microcontroller is an integrated circuit chip that contains a microcontroller circuit and some general input and output interface devices. From the perspective of the way of constituting the embedded system, according to the development level of modern electronic technology, the embedded system can be realized by a single-chip microcomputer or other programmable electronic devices. The rest of the hardware components are based on the needs of the target application system.

The difference between single-chip microcomputer and embedded in software composition:

The manufacturer's general-purpose microcontroller does not have an application in it, so it cannot be run directly. With the addition of applications, the microcontroller can run independently. Embedded systems must have control software, and the way to implement the control logic can be completely with hardware circuits or software programs.

The difference between single-chip microcomputer and embedded in the primary and secondary relationship:

The microcontroller is now considered to be a universal electronic device, and the microcontroller itself is the main body. Embedded systems are physically subordinate, and embedded systems are embedded in the target application system. The embedded system is dominant in the control relationship, and it is a logical processing system that controls the operation of the target application system.

Although an embedded system can be composed in different ways, once it is built, an embedded system is a specialized system. In a dedicated system, the software of the programmable device can be embedded during the system construction process or generated directly during the device manufacturing process to reduce manufacturing costs. MCUs with complex control logic require operating system software support; Embedded systems with simple control logic can also be supported without operating system software.
