Trusted computing chip blockchain
This is two different concepts. According to different standards, blockchain can be classified into three categories:
& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain
&# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain
&# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain
the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process
Blockchain, which has been busy for four months, is hot almost at the first touch. From the capital craze to we media cluster, now hardware manufacturers are also planning to take a share
as of April 12, Lenovo's block chain mobile phone S5 has been on sale for about 20 days. This thousand yuan machine mainly uses "blockchain" protection technology to ensure payment security< in addition to Lenovo S5, candy S11 and Changhong R8 Qilin also label blockchain mobile phones, and claim to have blockchain wallet, mobile phone mining and other functions
in the view of a number of technicians and instry insiders in the blockchain instry, the above-mentioned blockchain concept mobile phone does not make clear what specific blockchain technology is applied. The so-called encryption function is vague, and its technology is also applied in ordinary mobile phones. However, because the computing power of mobile phones is completely difficult to compete with mining machines, "mobile phone mining" is not realistic
however, it is not impossible for blockchain to be applied to smart hardware such as mobile phones“ If it is clear how to integrate the blockchain into the hardware, how many nodes there are, and what consensus mechanism and encryption means are used, the public will be more convinced. " Cao Yin said
Zhao Yongliang, vice president of Shandong blockchain Application Technology Research Institute, analyzed that after the development of smart phones in recent years, they have encountered a bottleneck. For some non head traditional manufacturers, there is no new growth and innovation, "in this respect, blockchain mobile phones are more like a gimmick."
The main differences between 7Nm and 10nm are as follows:
1, gate length is different. The width of the gate formed on the CPU is also called the gate length. The 7Nm process can integrate more transistors into CPU and GPU, and make the processor have more functions and higher performance
2. Different power consumption. For 7Nm technology and 10nm technology, the volume of 7Nm will be smaller when the same number of transistors are plugged. The large volume of 10nm, because of the process problems, will lead to the larger capacitance of the original, the required voltage is higher than 7Nm, resulting in higher overall power consumption
performance:
the chip is composed of transistors. The smaller the process, the more transistors in the same area of the chip, and the stronger the natural performance. The performance of 7Nm is better than that of 10nm
take Huawei Qilin 980 as Qilin 970, where Qilin 980 is a chip with 7Nm process and Qilin 970 is a chip with 10nm process
first look at the number of transistors, Kirin 980 has 6.9 billion transistors, Kirin 970 has 5.5 billion transistors, an increase of about 25.5%. In terms of performance, it's not as simple as 25.5%, because it involves not only the number of transistors, but also the upgrade of CPU, GPU, NPU and other IP cores
in terms of specific values, for example, the running points of CPU, Qilin 980, GPU and NPU are about 50% higher, twice as high
extended data:
integrated circuits have two main advantages for discrete transistors: cost and performance. The low cost is e to the fact that the chip prints all the components as a unit through photolithography, rather than making only one transistor at a time. The high performance is e to the fast switching of components, which consumes less energy, because the components are small and close to each other. In 2006, the chip area ranged from a few square millimeters to 350 mm, with a million transistors per mm
it should be noted that this is the recharge price. If it's selling q-coin, because q-coin recycling is now done by some third-party platforms, there will be a certain cost. Therefore, the recovery price of Q coin is generally lower than the recharge price, remember!
equipment maintenance refers to the technical activities carried out to restore the function of the equipment after its technical condition deteriorates or fails, including all kinds of planned repair, unplanned fault repair and accident repair. Also known as equipment repair
the basic contents of equipment maintenance include: equipment maintenance, equipment inspection and equipment repair.
