Cbck digital currency
recently, I read a book called bitcoin, which was written by Li Jun. in the book, I introced the generation and development of bitcoin. The content is: bitcoin was born in 2009. Bitcoin is a kind of electronic currency which is generated by cipher coding and a lot of calculation of complex algorithm. Although it is a virtual currency, bitcoin has attracted unprecedented global attention
this string of numbers condensing encryption algorithm and computing power can not only be safely circulated and exchanged for physical objects, but the value of 1 bitcoin was even as high as 8000 yuan. Some researchers believe that bitcoin has the possibility to break the monopoly of global currency issued by the state for thousands of years. Inadvertently, the new financial wave caused by bitcoin has quietly taken shape
this momentum seems to have great business opportunities, but I personally have a sense of uneasiness. After all, the law of history is like this. When the water is full, the moon will overflow and the moon will lose. Therefore, caution is necessary. Although I have not yet included in the field of bitcoin investment, I am a very rational investor, and I will not easily set foot in it, just like stocks, If you don't, you'll be ruined. I would like to draw your attention
virtual currency is not new. Why is only bitcoin so popular? Its volatile price makes investors worry more: what is the reasonable price of bitcoin? Where is the price support system? Is such a sharp fluctuation a sign of its instability and eventual collapse
in response to the above questions, I read the author's answers, and I think what I said is very pertinent. After all, it's a person who has gone through a bloodbath in the bitcoin market, and I still admire big brother Li. I also learned a little knowledge of investment in it, so it's good to verify it again in the future investment
after reading the book, I have a great feeling that economy is economy, which is very complicated. I am not an economist, but a common people. I am cautious in investment, but I have to be bold and careful, and I will gain something. Even if I fail, it is also a kind of experience. Don't regret, but be smart.
The problem is that the new process uses high-pressure stress testing for evaluation. This kind of testing is very effective in obtaining statistical prediction data of oxide film life and detecting important manufacturing and technological difficulties, but it has little effect in modeling and predicting early failure of procts, especially for occasional failure. The initial breakdown will cause serious failure consequences in a short time after the device is put into use
finding and eliminating the causes of these initial breakdown faults is a big challenge. The true breakdown life limit of oxide film can be obtained by testing and verifying TDDB data, but these data are not reliable in determining the life of a single device proct
even if semiconctor suppliers have ways to identify or eliminate early failures, it is increasingly speculated that the true life cycle of 90nm devices may not be enough to meet the requirements of many commercial applications. If these theories are correct, automotive proct designers may have no choice but to specify devices based on more reliable geometry and process, and be forced to give up the marginal benefits of the new generation process in order to improve reliability
bus line: 2 fast, the whole journey is about 6.4km
1. Walk about 3.7km from Zaozhuang high-speed railway station to mining group station
2. Take 2 fast, pass 3 stops, reach bus station
3. Walk about 190m to Xuecheng bus station
if you have many functions to implement (such as MAC learning, adaptive, PHY, l2sw, etc.), your selected FPGA may cover from the lowest end to the highest end.
Intel's team also pointed out that in addition to DNN, FPGA has broad prospects in various delay sensitive applications (such as automatic driving assistance system and instrial system).
