bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

5g will become the most frequently used word in 2020. In the past year, 45 telecom operators around the world have begun to deploy 5g. Obviously, 5g will change our lives at a speed far faster than 4G. As the world's largest mobile phone chip supplier, at this CES, Qualcomm also showed its overall layout of 5g era for the first time, initially completing the comprehensive coverage of mobile phones, computers, cars and cloud

different from the previous press conference in which mobile phone business occupied the C position, the biggest space of this CES press conference of Qualcomm was about the automobile business. For the first time, the automotive field has become the focus of Qualcomm's layout. In addition to the Internet of vehicles business that has been laid out before, this time, Qualcomm has also extended its tentacles to automatic driving

automatic driving platform with more flexibility and lower power consumption at the press conference of Qualcomm on the eve of CES, Qualcomm officially launched the new snapdragonride platform, officially listed various problems encountered in current automatic driving, and said that its own platform is one of the most advanced and scalable open automatic driving solutions in the automotive instry. This kind of scene is like, one day, a former mobile phone chip maker suddenly stood in front of a pile of car Tier1 and sighed: "there is no one who can take a taxi. I have to come to the automatic driving solution."

with the development of 5g and artificial intelligence technology, more and more technology companies have joined the automotive instry, using the advantages of chips and software to enable intelligent vehicles and accelerate the intelligent and networking process of vehicles. Perhaps, owning a more intelligent and convenient car will come true earlier than we think

About

} are black sesame CEO and coo Liu Weihong

black sesame CEO. Previously, he was a member of the founding team of omnivision, a global vision chip leader. He has worked in Silicon Valley chip instry for more than 20 years and has rich experience and technology accumulation in image processing chip and software algorithm

CTO Qi Zheng is the main design member of Intel Pentium II chip, CSO Zeng Daibing is the chief engineer of ZTE microelectronics, and coo Liu Weihong was the president of chassis and control system division of Bosch China ADAS

because of its strong R & D team, heima, a start-up company, can make the ADAS chip huashan-1 A500 within three years and launch it in mass proction. This year, it will launch huashan-2 a1000 chip and launch the fad automatic driving platform

since the beginning of this year, if new cars are not equipped with L1 / L2 automatic driving, they are "embarrassed to sell", the popularity of automatic driving is rapidly increasing, and the higher level of L3 or even L4 automatic driving is on the eve of mass proction, and the demand for automatic driving chips and computing platform solutions in the instry is explosive growth. The market scale of autopilot chips alone is expected to reach trillion US dollars, becoming the largest single market in the semiconctor instry

Therefore, it is right time for fad to enter the automatic driving market

in August this year, FAW Intelligent Network Development Institute reached a technical cooperation agreement with heima. FAW Intelligent Network Development Institute will start the development of intelligent driving platform based on huashan-2 a1000 to meet the demand of subsequent mass proction models. The two sides will jointly promote the application of artificial intelligence technology in the automotive instry and accelerate the instrialization of domestic intelligent driving chips

in addition, heima has signed a number of fad fixed-point models, and it is expected that there will be models equipped with fad automatic driving platform on the market next year. In addition, many enterprises at home and abroad have begun to test fad automatic driving platform, and the test vehicles have been on the road

the great success of black sesame in automatic driving chip and domain controller makes instry research institutions begin to pay attention to this start-up company which has just been established for more than four years. In April this year, cbinsights, one of the strongest think tanks in Silicon Valley, released the list of Chinese chip design enterprises. Black sesame was listed in the field of vehicle chip, becoming one of the top 65 Chinese chip design enterprises

in July this year, black sesame Huashan No.2 a1000 chip also appeared in the world artificial intelligence conference, together with pingtouge, Yitu, Cambrian and other high-end artificial intelligence chips

it can be said that after more than four years of development, black sesame has become the world's leading autopilot chip design company, and even has the ability to compete with the eldest brother in the chip instry. At the same time, the rapid progress of black sesame also promotes the domestic automatic driving chip design to a new level

in the conversation with the two founders, they also revealed a colorful egg. Next year, hei mahjong will release a chip with stronger performance. At that time, the highest computing power of fad automatic driving platform equipped with this chip is expected to exceed 1000tops, and its computing power can be fully automatic driving

The differences between Apple's A10 chip and A9 chip are as follows:

1. The running score data shows that the single core running score of Apple's A10 processor has reached 3000, which is comparable to that of Apple's a9x processor, and has increased by about 20% compared with that of Apple's A9 processor

2. In terms of GPU graphics processing, apple A10 chip is two-thirds higher than apple A9

3. Apple A10 chip adopts 6-core design and 14 nm proction process, while Apple A9 chip still adopts al core design

In terms of battery life, because Apple A10 chip adopts 6-core design, its power consumption is much larger than that of Apple A9, which is the problem apple must consider to solve

Apple A9 processor model is apl1022, which is packaged with Hynix 2GB lpddr4 ram. Apl1022 is manufactured by TSMC with 16nm FinFET process. The packaging area of 16nm A9 processor is larger than that of 14nm A9 processor

6. The number of Apple's A10 processor core is tmgk98, which continues the A9 tmgk96. The core area is about 125 square mm. The package uses TSMC's latest FIFO technology and is more compact than before. It is said that there are 3.3 billion transistors

extended materials:

at the launch of iPhone 7 and iPhone 7 plus, apple officially released the new chip A10 fusion, a 64 bit processor with a performance of "little rocket". A10 fusion is the first apple four core processor with 3.3 billion transistors. The CPU is 40% faster than the A9 processor of the iPhone 6S, twice as fast as the A8, and 120 times faster than the iPhone generation

the GPU of Apple's A10 chip has also been updated, which is 50% faster than that of A9, three times faster than that of A8 chip, and 240 times faster than that of iPhone generation. Apple's A10 fusion processor can bring "console level Games", and Lightroom will support raw image editing and so on

9. Botai mobile is 20 times faster than the traditional Internet of vehicles. Many people think it's bragging. In fact, it's not. It's just a fact. Just from the calculation power of hardware, we can draw a conclusion. According to the evaluation of authoritative media, the average score of car chip is about 20000, but how much can smart phone chip reach? It's close to 400000, and the computing power of the chip is totally 20 times lower. Smart phones also have powerful GPU image chips and AI chips, while more than 95% of IOT procts do not have GPU and AI chips at all. In terms of hardware, mobile phones have inherent advantages in realizing IOT as terminals. At the same time, the speed of vehicle replacement can not be compared with that of mobile phones. Based on different speeds, mobile phones have more experience advantages in IOT, Speech recognition can be faster and more accurate, software functions and hardware control can be more abundant, and more complex intelligent algorithm control can be realized. The use scene and time of the Internet of vehicles (IOT) have changed from 2-hour system to 24-hour system, which is incomparable with the traditional IOT system.
