Silicon Valley will be a Monday morning, people do not want to get up in the face of hard work where there is a ready example ──, according to recent Bloomberg (Bloomberg) reported, Aicha Evans Intel (Intel) wireless business group manager had left.

I had a chance encounter, according to Intel official data 20 years seniority Evans, as an African woman engineer, she can get on top of Intel’s position is obviously very competent professionals. According to various stories, Evans in the last few months of his career especially hard, because it is responsible for the operation situation of poor Intel wireless business.

Intel for many years actively trying to heat beyond laptop mobile phone market to expand their territory, including its ambitious acquisition and sale deeds StrongARM processor, designed its own flash memory containing the function blocks cellular phone chips, and It has acquired the iconic cellular phone modem chip business Infineon (Infineon) wireless business group.

Originally responsible for Infineon’s wireless business business group Hermann Eul last to leave, Evans was his successor; Evans on behalf of Intel to attend last year’s Mobile World Congress (Mobile World Congress, MWC), said the company will data 5G machine chip lead, but in view of the first edition 5G standards may be by the end of 2018 will come out, as though daring goal but also very far away.

So, why Evans left the company so soon? If she really leave the words … this Intel declined to comment, Evans himself did not respond to messages sent by the author, and the industry has all kinds of speculation on this post …

The Motley Fool tech community site speculated that this is because the business group Evans trouble shipping 14-nanometer versions of Intel integrated applications processor SoFIA year; but I’m not sure whether her department is responsible for the chip.

Market research firm Forward Concepts Leader Will Strauss speculated, Evans is leaving the department because she did not get the iPhone case design 7; however Bloomberg reported citing a Wall Street analyst speculation that Intel will get at least part such a large number of high-value design case.

Of course, unless Apple (Apple) of the minority as well as some key suppliers, no one really knows the answer; but it was still too early, things could still change. In Steve Jobs (Steve Jobs) is still Apple, when I heard that the company had to abandon the use of a component, because vendors say too much should not say.

One thing is very clear, the smart phone modem chip market is not easy to break; Qualcomm (Apple) in the market 58% market share, such as Strauss said, this is because the company will be pretty all the latest 3GFPP function together, and can quickly introduce new designs. Qualcomm is currently the 12th generation chip support 600 Mbits / s download speed, and has been discussed in the next generation (xiii generation) chips will reach Gbit / s level.

And close behind MediaTek (MediaTek) the market share of 20 percent, China’s Spreadtrum (Spreadtrum), compared with 6% market share; both companies are good at cutting costs, and outstanding performance in the Chinese mobile phone market.

Phone modem chip market is so steep, market share ranked fourth and fifth supplier (respectively 6% and 3% of Marvell Broadcom) have quit last year; and Strauss noted that Chinese telecommunications equipment maker Huawei ( Huawei) also has a very good LTE modem chip, the chip supplier’s Hass (HiSilicon) design.

Intel in the mobile phone modem chip market share of only 1%, and should be spent billions of dollars to maintain the business; therefore Evans in the past few months will indeed be on pins and needles. I really hope one day to hear her own experiences, that would be great Silicon Valley story.

In Silicon Valley, there are many super smart guy trying to complex, rapidly changing global market perform some incredible feat, and that the story of what I turn on the computer trying to accomplish tasks every Monday morning!

Researchers at the University of Georgia and Gurion University of the Negev in Israel by DNA molecular manufacturing a new type of diode. This is considered to be the world’s smallest size diode. The researchers said it would promote the development of DNA components, and promote the development of molecular electronics. The function of the diode is to realize the unidirectional flow of current. More than 40 years ago, scientists have suggested that the diode and other electronic components can be miniaturized, reduced to a single molecular size. This has led to the birth of molecular electronics, and the research results of molecular electronics is expected to promote the computer technology to break through the limitations of traditional silicon devices.

In this study, the scientists used DNA to create a diode. The breakthrough of gene science makes it possible to design DNA accurately, and makes DNA become the best raw material in the study of molecular electronics.

The double helix structure of DNA consists of molecules called the base pair. The length of this new type of diode is only 11 base pairs. Typically, the length of each DNA base pair is about 0.34 nm.

DNA itself does not play the function of the diode. However, when the researchers to a position of the internal DNA insert two small Coralyne molecules, and to the applied 1.1 volts, can be found in the current through the diode of the DNA in a certain direction to 15 times stronger than in the other direction.

The scientists said that this DNA diode can be further optimized, so as to develop a molecular device can provide the actual function. The research is published in the journal Nature chemistry.

In order to solve the calculation problem of the world’s most intractable, the Lawrence Livermore National Laboratory, Lawrence Livermore National Laboratory) hope to obtain inspiration from the structure of the human brain, so the laboratory program in this month 31 days to a value of $100 million super computer testing. It should be pointed out that this super computer is the most special place is the integration of the 16 dedicated to simulate the work of the human brain processor.

It is reported that the use of this super computer processor chip called “TrueNorth” by the IBM in 2014 for the first time introduced. In fact, IBM, Qualcomm and Microsoft had previously teamed up to design, develop a computer algorithm to improve the processing speed of the chip. And such as “TrueNorth” is more suitable for this type of chip is applied to advanced artificial intelligence technology, including in-depth study. It should be noted that this chip technology is actually a model of the human brain to run a simulation, although it has not yet been tested, but its future prospects are very attractive.

Specifically, the “TrueNorth” chip and the current server or personal computer used in the chip has a very big difference. The chip set up 5 billion 400 million transistors, which constitute a network of 1 million simulated neurons, which are connected by a large number of analog synapses. Moreover, IBM is mainly used in the United States Department of Defense Advanced Research Projects Agency (DARPA) under the funding to develop TrueNorth chip.

Engaged in truenorth research and development work has been 12 years of IBM’s chief researcher de Harmon della – Modha DharmendraModha said “although in some degree, the structure of the brain looks quite simple, but it can solve some complicated problems.” say。

IBM revealed that it is now five to seven years away from the commercial TrueNorth large-scale investment, but the Lawrence Livermore national laboratory test is an important step in this direction taken an important step.

Similar to the human brain, TrueNorth does not need to consume a lot of energy at run time. For example, the average server chip power consumption of more than 150 watts, while the power consumption of TrueNorth chip is only 2.5 watts. However, TrueNorth can not be used to run the web server, and even can not be completed in a Excel table in the work of several columns of data input. This is mainly because the chip is designed is to perform such as image recognition, or is a kind of artificial intelligence application (such as the recent Google (micro blog) parent company alphabet software AlphaGo beat South Korea chess master Li Shishi that era of computing tasks.

“TrueNorth will be very useful for deep learning applications and for a wider range of machine learning applications.” Van Essen Brian, a computer scientist at the Lawrence Livermore National Laboratory, said.

In fact, Lawrence Livermore national laboratory as early as 2014 began to assess the TrueNorth, but this is the first time the chip has the opportunity to start large-scale testing. Van Essen says his team will be part of the super computer operation gradually transition to truenorth tested, like today, there are many PC will graphics processing of transition to the graphics card to deal with the same principle. He hopes that this technology can help solve problems such as interactions subatomicparticle and network security and other complex issues such as sub atomic particles.

On the other hand, the Lawrence Livermore National Laboratory launched the test for IBM is also an important stage to prove the practicality of TrueNorth.

“They do this very well, TrueNorth may be very efficient, but they still need to prove the accuracy of the model.” University of Washington, associate professor of computer science Sezi – Lewis (Luis Ceze) said.

It should be noted that, IBM is not the only one in the field of computer depth learning to set off waves of enterprise. Currently, Qualcomm is developing its own intelligent cognitive platform Zeroth, the technology allows mobile devices have the innate ability to learn, and do not need to get data through the cloud. For example, Zeroth can identify specific parameters in a picture, so people can use the phone for a specific photography. In addition, users can also use Zeroth technology to identify the picture in the face. More important is that in contact with enough pictures and human face, Zeroth technology will become more and more intelligent.

At the same time, Microsoft researchers are also being launched to allow the programming chip with the company’s Bing search engine to start a collaborative work.

“The race to build a new era of computing chips has already begun. To be honest, we’re still in the lead.” Modeha said.
