Front end computing power
take the flagship SUV Mocha, which represents the brand new development direction of wey, as an example. At the end of 2020, great wall just released lemon hybrid DHT technology and intelligent travel solution coffee intelligent drive, which will be the first to be carried on this vehicle
especially automatic driving technology. Some people compare it with the new car et7 released by Weilai on NiO day. For example, on et7, which will be officially launched a year later, Weilai will carry lidar for the first time. Wey is already equipped with German ibeo next 4D solid-state lidar on Mocha, which will be launched in a few months
for another example, the high-tech 8155 smart chip used in mocha is also known by netizens as "the most powerful computing power on the surface". It is said that this chip is the first digital cockpit chip made by 7Nm technology. It has a new learning neural network processor NPU, and has AI Artificial Intelligence deep learning ability. Compared with the previous generation, the performance of CPU and GPU has been improved by 8.5 times and 20 times, respectively. Compared with the car chip of ideal one and Xiaopeng P7, the performance has been improved by 3 times
advanced hardware is only one aspect. Previously, at the coffee smart drive press conference, great wall also showed its own research and development of Noh (navigation on highway pilot, Chinese name "high-speed automatic pilot assisted driving") for full scene coverage of high-speed and urban expressways. This system will also be carried on mocha
this also makes wey the first traditional car company to launch similar functions after Tesla's NOA, Weilai's NOP and Xiaopeng's NGP

seek the optimal solution between mileage anxiety and environmental protection problems
in the past, in the impression of most people, intelligent vehicles are often equated with pure electric vehicles. However, at wey's brand new launch, lemon hybrid DHT was used as another major technical support to create a new label
according to song Dongxian, vice president of Great Wall Motor Technology, although the external acceptance of electric vehicles is getting higher and higher, there are still some inherent defects in the use of electric vehicles e to the imperfect infrastructure. Through the lemon hybrid DHT technology, Great Wall hopes to solve the mileage anxiety of electric vehicles and optimize the shortcomings of the original HEV and PHEV technologies criticized by consumers, so as to be closer to the actual needs of consumers
for example, in view of the problems of slow charging and short driving range of PHEV models in the past, great wall can achieve the maximum pure electric driving range of 200km through fast charging technology and increasing battery pack, which fully meets the daily commuting use
as for HEV models, song Dongxian said that compared with similar Japanese procts, they also have some advantages“ Wey brand with lemon hybrid DHT model, the biggest advantage is fuel saving, energetic, fast response
for example, unlike some Japanese hybrid models which are suitable for urban driving but lack of power advantage on high speed, it is said that Mocha's 1.5T model, equipped with P4 motor and DHT, has a total power of 320 kW and strong power
generally speaking, through the application of lemon hybrid DHT technology, wey hopes to find the optimal solution between mileage anxiety and environmental protection. It weakens the trade-offs made by consumers e to power system problems when buying a car

traditional car companies also began to pay attention to "people"
"the arrival of mocha will promote traditional car manufacturing to enter the forefront of the intelligent era, and there will be no" new "or" old "forces from now on."
wey has high expectations for the brand new flagship model launched after the brand renewal
However, apart from the label of intelligent technology, how to treat users is also a big difference between the "new" and "old" forces In this regard, Qiao Xinyu, deputy general manager of wey brand marketing, frankly said, "the biggest difference between the new force of car building and traditional car building enterprises is that they focus on users and make friends with users.". However, after recognizing the difference, "wey brand has been practicing this concept in recent years," he said In wey's opinion, the "new" concept of "new generation intelligent vehicle" proposed this time is mainly reflected in "people-oriented"according to Chen Xianling, digital executive officer of Great Wall Motors, in 2020, Great Wall established a proct digital center, under which a user experience center was set up to integrate user experience into the proct development stage
take some user scenarios of mocha as an example. In addition to the functions of VIMS face recognition, Hwa + AVP vehicle and environment perception, L3 level high-speed automatic driving, gesture moving and so on, mocha's intelligent service system can also monitor the vehicle status at any time, remind and help the vehicle owner to make an appointment for maintenance. If you have any questions in the process of using the car, you can always connect with experts who understand the car to answer them
in addition to the vehicle itself, through the owner's app, the person in charge of each segment of wey brand will also communicate directly with users every day. Users can also participate in the co creation of car body color, car configuration and other issues
in Qiao Xinyu's words, the operation idea of wey brand is "changing from managing procts to managing users". In their planning, the concept of "people-centered" will continue to expand in the future

written at the end
"in the past 30 years, Great Wall Motor has built a successful national shenche haver. In the next 30 years, Great Wall Motors will build a successful wey. "
It is said that this is the expectation of Wei Jianjun, chairman of Great Wall Motors, for the future development of the brandnowadays, great wall has not disclosed too much about the specific confidence of mocha models. However, from hard core intelligent technology to humanized proct building concept, wey after brand renewal has a relatively clear direction compared with before
According to wey's plan, mocha will be available at the end of March. At that time, the new effect of wey brand will be fully tested by the market< br />7850 or above, the number of video card stream processors x, frequency and speed are directly proportional
for example, the 7850 and 280x also run at 1000MHz, and the speed of 280x is twice that of 7850

the daily cash withdrawal limit of ATM is 20000 automatic teller machine, also known as ATM, is the abbreviation of automatic teller machine, which means automatic teller machine. Because most of it is used for withdrawal, it is also known as ATM. It is a highly precise mechatronics device, using magnetic code card or smart card to achieve self-service of financial transactions, instead of the work of bank counter staff. It can withdraw cash, inquire deposit balance, transfer funds between accounts, inquire balance, etc; It can also carry out cash deposit (real-time entry), check deposit (none in China), passbook re registration, intermediate business, etc. Cardholders can use a credit card or savings card to make automatic withdrawal, balance inquiry, transfer, cash deposit, passbook re registration, purchase funds, change passwords, and pay mobile phone bills according to their passwords
different ATM settings are different, some are single transaction 2000, some are 2500, 3000, at most 5000 per transaction; At the time of withdrawal, ATM will prompt the maximum amount of each withdrawal
On June 21, 2019, xinbaojun mobile Internet of vehicles media sharing meeting was held in Nanjing. The first Internet of vehicles without mobile phones shocked everyone
the driving role of the Internet of vehicles technology in the automotive field has been significantly strengthened, which promotes the development of the automotive field. This is the growth space of related instries represented by the Internet of vehicles. After that, with the development of mobile Internet, the arrival of big data, Internet of things technology and new technology, it has brought more growth opportunities to the Internet of vehicles
some people say that with the advent of the era of Internet of vehicles, the curtain of artificial intelligence such as driverless, remote control and VR / AR has really opened. For us, the world is full of unknown and hope
in the final analysis, the arrival of the Internet of vehicles is still the competition of hard power and high technology
Because the performance of processor is an absolutely important factor affecting the computing power, we divide the computing power into three types according to the different types of processor: ordinary type, superior type and powerful type The following example is a system n years ago, which is obsolete.) Processor types: Intel celeron-m (Dothan core), Intel celeron-m (yonah core), mobile AMD Sempron
configuration of other components: 256MB memory, 40Gb or 60GB hard disk, integrated graphics card, interface with one disk
relative price range: 4000-6000 yuan
model recommendation: (unfinished)
special case: in ordinary computing notebook computers, e to the high cost of design and R & D, the price of light and thin models with beautiful appearance will increase to a certain extent. Processor type: Intel pentium-m (Dothan core, including 400MHz front-end bus and 533MHz front-end bus), mobile AMD turion 64< Other components configuration: 512MB memory, 80GB or 10GB hard disk, independent or integrated graphics card, general interface
relative price range: 5000-7000 yuan. Model recommendation: (unfinished)
special case: among the notebook computers with excellent computing power, the price of procts with higher independent graphics card specifications will be increased to a certain extent. Processor types: Intel Core solo / o, Intel Core 2 Duo, mobile AMD turion 64 x2< Other parts configuration: 1GB or 2GB memory, 100GB or 120GB hard disk, independent graphics card, rich interface
relative price range: 6000-13000 yuan
model recommendation: (unfinished)
special case: in notebook computers with strong computing power, the price of procts with top hardware configuration will increase to a certain extent. For example, ThinkPad workstation t60p
the reason why it is a "relative" price range lies in the following points:
1. There is a price war in the notebook market, because the more obvious the price advantage of the same configuration model is, the more attractive it is to consumers
2. Other configurations are different, such as memory capacity, hard disk capacity, graphics card type and specification, interface richness, display screen size and display effect, and fuselage material
3. In terms of accessories, operating system and after-sales service are attached (affected by the length of service life)
1. Main frequency: that is, the clock frequency of CPU, in short, the working frequency of CPU. The higher the main frequency, the faster the CPU speed. Generally speaking, Celeron 433 and PIII 550 refer to the main frequency of CPU
2. Bus speed: generally equal to the external frequency of CPU. The speed of memory bus is very important to the performance of the whole system. In order to alleviate the bottleneck brought by memory, two-level cache appears to coordinate the difference between the two. The speed of memory bus refers to the working frequency between CPU and L2 cache and memory
3. Working voltage: that is, the voltage required for the normal operation of CPU. In the early days, the working voltage of CPU (386 and 486) was generally 5V. When it developed to Pentium 586, it was already 3.5V, 3.3V and 2.8V. The latest Coppermine proced by Intel has adopted the working voltage of 1.6V
4. Coprocessor: the main function of coprocessor is responsible for floating-point operation. Since 486, CPUs generally have built-in coprocessor, and the function of coprocessor is no longer limited to enhancing floating-point operation. Nowadays, the floating-point unit (coprocessor) of CPU often optimizes multimedia instructions
Pipelining technology: pipelining is the first time that Intel began to use in 486 chip. The assembly line works like an assembly line in instrial proction. In the CPU, an instruction processing pipeline is composed of 5 ~ 6 circuit units with different functions. Then an x86 instruction is divided into 5 ~ 6 steps and executed by these circuit units respectively, which improves the operation speed of the CPU6. Hyper threading: multiple threads can be executed at the same time, which can make the CPU play a greater efficiency and rece the waste of system resources. One CPU can be simulated as two CPUs, and resources can be used more effectively at the same time to improve performance
Process technology: the smaller the process, the smaller the calorific value, so that more transistors can be integrated and the CPU efficiency will be higher8, 3-level cache
L1 cache (first level cache): the first level cache of CPU is divided into data cache and instruction cache. When the CPU chip area is not too large, the capacity of L1 cache can not be too large. The L1 cache capacity of general server CPU is usually 32-256kb
L2 cache: it is the second layer cache of CPU, which is divided into internal and external chips. The internal chip's L2 cache runs at the same speed as the main frequency, while the external L2 cache only runs at half of the main frequency. Now it can reach 2m in notebook computers, and the L2 cache of CPU on servers and workstations is higher, which can reach more than 8m
L3 cache: it can be divided into two types: external cache in the early stage and built-in cache in the present stage. Its practical function is that the application of L3 cache can further rece the memory latency and improve the performance of processor in large amount of data computing

Data: the physical symbols or the combination of these physical symbols that record the nature, state and relationship of objective things, also include numerical data and non numerical data
information is another form of data after data processing, which affects the behavior of the receiver to some extent. It has objectivity, subjectivity and usefulness
The relationship between data and information: information is the meaning of data and data is the carrier of information
data are numerical values, that is, the results obtained by observation, experiment or calculation. There are many kinds of data, the simplest of which is numbers. Data can also be text, image, sound, etc. Data can be used for scientific research, design, verification, etc
information refers to the objects transmitted and processed by audio, message and communication systems, and generally refers to all the contents transmitted by human society. By obtaining and identifying different information of nature and society, people can distinguish different things and understand and transform the world. In all communication and control systems, information is a form of universal connection
In 1948, the mathematician Shannon pointed out in his paper entitled "mathematical theory of communication" that "information is used to eliminate random uncertainty". Information is the most basic universal unit to create all things in the universehehe, hope to help you
