Computing power of MCU

MCU is the vehicle's navigation satellite receiving antenna, which is located in the engine compartment of the vehicle. It is used to receive the positioning satellite position outside the earth to provide position information for navigation. The specific operation steps are as follows:

1. Open the door on the side of the cab

The history of single chip microcomputer is not long, but it develops rapidly. Since the first 4-bit microprocessor was introced by Intel in 1971, its development can be divided into five stages. The development of Intel's single chip microcomputer is introced as a representative
1971-1976
the primary stage of the development of single chip microcomputer. In November 1971, Intel Corporation first designed a 4-bit microprocessor Intel 4004 with 2000 transistors / chip, which is equipped with RAM, ROM and shift register, forming the first mcs-4 microprocessor. Then it launched 8-bit microprocessor Intel 8008 and 8-bit microprocessor successively launched by other companies
1976-1980
low performance single chip microcomputer stage. Taking the Mcs-48 series introced by Intel in 1976 as an example, it adopts a single chip structure that integrates 8-bit CPU, 8-bit parallel I / O interface, 8-bit timer / counter, ram and ROM into a semiconctor chip. Although its addressing range is limited (no more than 4 KB), there is no serial I / O, the capacity of ram and ROM is small, and the interrupt system is simple, But the function can meet the needs of general instrial control and intelligent instruments
1980-1983
high performance single chip microcomputer stage. At this stage, 8-bit high-performance single-chip microcomputers are generally equipped with serial port, multi-level interrupt processing system and multiple 16 bit timers / counters. The capacity of on-chip RAM and ROM is increased, and the addressing range can reach 64 kb. Some on-chip also have a / D conversion interface
from 1983 to the end of 1980s, the stage of
16 bit single chip microcomputer. In 1983, Intel Corporation launched the high performance 16 bit single chip microcomputer MCS-96 series. Because of its latest manufacturing technology, the chip integration is as high as 120000 transistors / chip< In 1990's, SCM developed to a higher level in the fields of integration, function, speed, reliability and application
according to the characteristics of MCU, the application of MCU can be divided into single application and multi application. In an application system, using only one single chip microcomputer is called stand-alone application. The scope of single-chip application includes:
(1) measurement and control system. With the help of single chip microcomputer, various less complicated instrial control systems, adaptive control systems and data acquisition systems can be constructed to achieve the purpose of measurement and control
(2) intelligent instrument. The original measuring and controlling instruments are reformed by using single chip microcomputer to promote the development of digital, intelligent, multifunctional, comprehensive and flexible instruments
(3) mechatronics procts. The combination of single chip microcomputer and traditional mechanical procts simplifies the structure of traditional mechanical procts and makes the control intelligent
(4) intelligent interface. In the computer control system, especially in the large-scale instrial measurement and control system, the single-chip microcomputer is used to control and manage the interface, and the parallel work of the single-chip microcomputer and the host computer greatly improves the running speed of the system
(5) intelligent civil procts. For example, in household appliances, toys, game machines, audio-visual equipment, electronic scales, cash registers, office equipment, kitchen equipment and many other procts, the introction of single-chip controller not only greatly enhances the function of the proct, improves the performance, but also obtains good use effect< The multi computer application system of single chip microcomputer can be divided into function distributed system, parallel multi computer processing system and local network system
(1) functional distributed system. The multi-functional distributed system is a multi machine system set up to meet the requirements of various peripheral functions of the engineering system< (2) parallel multi computer control system. Parallel multi computer control system mainly solves the problem of rapidity of engineering application system, so as to form large real-time engineering application system< (3) local network system
single chip microcomputer can be divided into general type and special type according to its application scope. The special type is designed for a specific proct, such as single chip microcomputer for thermometer, single chip microcomputer for washing machine and so on. In the general-purpose single-chip microcomputer, it can be divided into 4-bit, 8-bit and 16 / 32-bit according to word length. Although the microprocessor of computer is almost 32 / 64 bit, 8-bit and 16 bit microprocessors tend to shrink, the situation of single-chip microcomputer is different. 8-bit single-chip microcomputer has low cost, low price and easy development. Its performance can meet most of the needs, only in aerospace, automobile, electronic instry In high-tech fields such as robots, 16 / 32 bits are needed only when a large amount of data needs to be processed at high speed. In general instrial fields, 8-bit general-purpose single-chip microcomputer is still the most widely used single-chip microcomputer at present
so far, the application of single chip microcomputer and the development of embedded system in China have gone through more than 20 years. With the graal penetration of embedded system into all aspects of social life, the teaching of single chip microcomputer course is also changing from the traditional 8-bit processor platform to the 32-bit Advanced RISC processor platform, but the 8-bit processor is still difficult to be replaced. National economic construction, military and household appliances and other fields, especially mobile phones, auto navigation equipment, PDA, intelligent toys, intelligent home appliances, medical equipment and other instries are in urgent need of SCM talents in China. At present, there are more than 100000 engineers engaged in SCM development and application in the high-end instry. However, in the face of the trend of embedded system instrialization and the opportunity of vigorously promoting the construction of "embedded software factory" in China, a large number of SCM application-oriented talents are in urgent need if China's embedded procts want to enter the international market and form an instry, This provides a great opportunity for higher vocational students to engage in this kind of high-tech instry

MCU in Avengers alliance is the abbreviation of Marvel cinematic universe, which is called Marvel movie universe and marvel movie universe in Chinese

MCU is the abbreviation of Marvel cinematic universe where Marvel's Avengers film series is located, and the universe number is earth-199999. MCU is a very young world. It has been ten years since it was born. In the future, it will continue to tell its own story until the end of the hero

Marvel cinematic universe (MCU) is a common overhead world centered on superhero movies, a series of films independently proced by Marvel studios based on the characters in Marvel comic publications. Like the main universe of marvel in comics, it is built by common elements, settings, performances and characters through cross-border works. Marvel television expanded the universe further, procing TV series in the universe

Relationship: MCU is in the CPU frequency and specification to do appropriate rection, and add memory to form a chip level computer

1. It refers to different

1. CPU: as the operation and control core of computer system, it is the final execution unit of information processing and program operation

3. Different classification

1. CPU: it mainly includes two parts, namely controller and arithmetic unit, which also includes cache memory and data and control bus to realize their connection. The three core components of electronic computer are CPU, internal memory and I / O device. The main functions of CPU are processing instructions, executing operations, controlling time and processing data
