Difference in terms of hardware composition Single-chip microcomputer is composed of an integrated circuit chip, specifically including single-chip microcomputer circuit and input and output interface controls. With the development of electronic technology, embedded can now be realized with both single-chip microcomputers and other programmable electronic devices.

Architectural differences Embedded development can be based on a variety of processor architectures, such as ARM, MIPS, PowerPC, etc. It usually uses operating systems (such as Linux and RTOS) as the basis and can run multiple applications or tasks. The hardware platform for embedded development is also relatively flexible, and different chips and peripheral components can be selected.

The difference between embedded systems and single-chip microcomputers: different hardware composition, different application objects, different system composition, different software composition, different primary and secondary relationships, different system connections, different hardware composition means that embedded systems can be realized with single-chip microcomputers or other programmable electronic devices. Single-chip microcomputers are A microcomputer system.

The difference between embedded and single-chip microcomputer Single-chip microcomputer and embeddedDifferences in system composition structure: (1) Basic structure of single-chip microcomputer Single-chip microcomputer is composed of operator, controller, memory, input and output equipment.

The scope of application is different, and the design ideas are different. Blue Bridge Cup single-chip microcomputer refers to the single-chip microcomputer technology used in the Blue Bridge Cup competition, which mainly includes the programming and application of single-chip microcomputers. Single-chip microcomputer is an integrated circuit chip with processors, memory and various input and output interfaces, which is suitable for various control and embedded systems.

Embedded programs are dedicated. Programs that directly control the hardware are generally written in assembly language and C language. PC programming, you mean the program on a personal computer. You can use C, C++, JAVA, C#, as needed. C and C++ are completely different languages with completely different basic ideas.

What is an embedded system?

1. According to the definition of the International Association of Electrical and Electronic Engineers, an embedded system is "a device used to control, monitor or assist in the operation of machines and equipment".

2. Embedded systems generally refer to non-PC systems, equipment or equipment with computer functions but not called computers. It is a special computer system that is application-centered, software and hardware can be reduced, and adapts to the comprehensive and strict requirements of the application system for function, reliability, cost, volume, power consumption, etc.

3. Embedded system means a special computer system designed for specific applications, which is completely embedded in the controlled device, for control, monitoring or auxiliary equipment, machines or equipment for factory operation.Embedded systems are used to control or monitor large-scale equipment, such as machines, equipment, factories, etc.

4. According to the definition of IEEE (Institute of Electrical and Electronic Engineers), embedded systems are "devices used to control, monitor, or a Ssist the operation of equipment, machinery or plants).

The components of the embedded system and the functions completed by each part

The embedded minimum system consists of three parts: the hardware layer, the intermediate layer and the system software layer.Specific introduction: Hardware layer The hardware layer includes embedded microprocessors, memory (SDRAM, ROM, Flash, etc.), universal device interfaces and I/O interfaces (A/D, D/A, I/O, etc.).

The embedded system consists of three parts: the underlying hardware module, the intermediate protocol layer and the high-end application layer.

It generally consists of four parts: embedded microprocessor, peripheral hardware device, embedded operating system and user's application, which are used to realize functions such as control, monitoring or management of other devices. Embedded system generally refers to a non-PC system, which includes two parts: hardware and software.

The main components of the embedded system: processor kernel: the heart of the embedded system is the processor kernel. The processor kernel is from a simpleFrom a cheap 8-bit microcontroller to a more complex 32-bit or 64-bit microprocessor, or even multiple processors.

In summary, an application system consists of five parts: master window, device window, user window, real-time database and running policy. At the beginning of the configuration work, the system only builds an empty framework for users that can run independently, providing rich animation components and functional components.

What are embedded processors and embedded systems?

The embedded processor is the core of the embedded system and the hardware unit that controls and assists the operation of the system. According to the British Institute of Electrical Engineers (U.K.Institution of ElectrThe definition of ical Engineer) is that the embedded system is the control, monitoring or auxiliary equipment, machine or equipment used for factory operation.

That is, Embedded Systems is a special computer system that is application-centered, microprocessor-based, software and hardware can be cut, and adapts to the comprehensive and strict requirements of the application system for function, reliability, cost, volume, power consumption, etc.

Embedded system is a special computer system as part of a device or equipment. A general embedded system is an embedded processor control board where the control program is stored in the ROM.

The embedded system is application-centered, based on computer technology, and the software and hardware can be cut, which is suitable forUse a special computer system with strict requirements for function, reliability, cost, volume and power consumption.

Embedded computer is a special computer technology that exists for a specific application such as network, communication, audio, video, etc. It consists of four parts: embedded microprocessor, peripheral hardware device, embedded operating system and user's application.
