Out of memory, CPU out of stock, and out of stock of hard drives will all be heard. However, in the past six months, the global GPU has been in a state of supply shortage. The first reason is that GPUs have now become the brains of artificial intelligence. The development of the artificial intelligence industry has brought a lot of demand; the second is that a large part of mining machines that mine cryptocurrencies are video processing machines. Lots of GPUs.                                                           GPU chip                GPU out of stock prices rose No one would have thought that the GPU, which is the core of game and image rendering, will appear to be out of stock for a long time, and the price will rise. According to some companies that do artificial intelligence, the latest GPU price has risen by 15% compared with six months ago, and it will be delayed by 4 weeks before delivery. This has had an impact on the research and development of artificial intelli

On the morning of May 29, Beijing time, Tesla CEO Elon Musk had a magnificent plan. In addition to developing hyperloops and landing Mars, Musk also wanted to change our road traffic. His latest plan is to expand the "Superchargers" network for Tesla's electric cars. He hopes to build more than 10,000 supercharged piles around the world by the end of next year, allowing Tesla owners to quickly recharge their vehicles anywhere, anytime. Musk posted a map in a recent tweet that identified the locations of all the supercharger stations to be constructed and the time of construction. At present, Tesla has built 1,200 supercharger stations worldwide, with a total of 9,800 supercharged piles. These charging posts can give Tesla vehicles 80% of their capacity in less than half an hour, but in some areas, the actual charging speed may not have reached this standard. Musk plans to change this, so that all regions of the Tesla Pull owners can enjoy speedy charging service. O

IoT is everywhere and although it is powerful, it also brings some challenges. Each sensing element is by definition an electronic device, and all electronic devices have in common the need for a power supply to operate. When deployed in small places such as homes and offices, it is relatively easy to power the sensors, whether they are wired or even button batteries that are replaced. However, due to the wide and wide deployment of environmental sensors, it is usually in remote and large spaces such as factories and buildings. Therefore, the use of wired power is inefficient, and replacing the battery is often inconvenient. In fact, the same problem exists with sensors that are embedded in near but hard-to-access areas such as the center of the machine. The number of sensors currently deployed is already in the billions, and this figure will only continue to grow, showing no sign of slowing down. So, how can this problem be solved? ON Semiconductor's smart passive sensor, Smar

With the development of power modules, engineers have focused on how to make modules smaller and lighter. In fact, we all understand that we can increase the power density of products by increasing the switching frequency. But why has the module's volume so far not changed so much? What restricts the increase of switching frequency? With the application of switching power supply products under the market, increasingly smaller, lighter, high-efficiency, low-radiation, low-cost and other characteristics are required to satisfy various electronic terminal equipments. In order to meet the current portable electronic terminal equipment, the switching power supply must be made small in size. Due to its light weight, it has become a matter of increasing concern for designers to increase the operating frequency of switching power supplies. However, what are the factors limiting the frequency of switching power supplies? In fact, it mainly includes three aspects: switch tubes, transformer

Nowadays, most mobile phones are pursuing the ultimate slimness, and the picky of the internal space of the manufacturers has caused the SIM card to be “seriously poisoned” for many times. However, technologies such as e-SIM cards have begun to become popular on wearable devices. Recently, ARM announced its own iSIM card, claiming that it can integrate SIM cards on ARM-based SoCs to further liberate mobile phone interior space. The SIM card is not unfamiliar to everyone. Everyone calls, sends text messages or uses cellular network functions. The SIM card service provided by the operator is indispensable—although the “complex” is small, it contains the user identifier IMSI, Key information such as the KI key and mobile phone number is an essential module for mobile phones. The iSIM card technology announced by ARM, including the securely encrypted hardware area of ​​the Kigen OS system, can not easily extract important data; at the same time, it also integrates the processor, bas

After a decade of plunging lamp prices, the wave of price cuts seems to be turning. According to foreign media reports, Acuity Brands, the largest luminaire manufacturer in the United States, has experienced significant price increases for the first time in many years, which has surprised the global lighting industry. Acuity Brands has several top brands in North America and Europe, including Lithonia, Winona, Holophane, Hydrel, Carandini, Gotham, Indy, Peerless and eldoLED, with annual sales exceeding US$3.5 billion (about 22.17 billion yuan). Acuity Brands announced that it will increase all traditional lighting technologies and a variety of LED products by 6% in price in the United States starting June 11. A British manufacturer said that Acuity's move can be seen as a "turning point." “We have been absorbing cost pressures because we cannot pass on price increases to our customers. But now we have reached a point where the installation of lamps is more expens

Intelligence itself is a "familiar and difficult to understand" vocabulary. The approximate explanation is this: The process from feeling memory to thinking is called “wisdom”. The result of wisdom is behavior and language. The process of expressing behavior and language is called “ability.” Both are collectively called “intelligence” and they will feel, The entire process of memory, recall, thinking, language, and behavior is called the intelligent process. It is the manifestation of intelligence and ability. They can use "IQ" and "Energy" to describe their degree of intelligence in individuals. In simple terms, we can attribute it to wisdom + ability, measured by IQ and emotional intelligence, and even more straightforward, that is, to what extent you are smart + how much you have. So how do we understand the "smart" of smart homes? According to some current industry arguments, smart homes will generally go through four stages of develop

At this year's InfoComm show will be a new 8K laser projector debut, this product uses a solid-state laser light source, the brightness reaches more than 20,000 lumens. In fact, this is not the first show of the 8K projection, as early as the end of last year, 8K projection has already entered the public view. Although frequently appearing at the show, I believe that 8K projection is still far away from ordinary users' lives. Because at the end of last year, 4K only ushered in the popularity of the home projection field. Now whether it is a product or supporting technology, 8K projection has a long way to go in the home field. Technology is immature The first problem with 8K projection is the chip. Currently, the mainstream projection products on the market are divided into two camps: DLP and 3LCD. The core technology of DLP projectors is in the hands of the Texas Instruments factory in the United States, and the core technology of 3LCDs belongs to Epson. Until today,

LCD panel maker Japan Display announced that they have developed a 3.25-inch display with a pixel density of up to 1001ppi. This display panel is mainly used for virtual reality helmets, not only has a higher picture quality, but also reduces the size and weight of the device. At present, the screen pixel density of HTC Vivo Pro is the highest among the same type of products, but it is only 615ppi. In comparison, HTC Vive is 448ppi, Oculus Rift is 461ppi, and Sony's PlayStation VR is only 386ppi. In addition to the ultra-high pixel density, Japan Display's display response time is reduced to 2.2 milliseconds, the refresh rate is 120Hz, and the resolution is 2160x2432. In contrast, the PlayStation VR has a resolution of 1920x1080 while the HTC Vive Pro has a 2880x1600. Considering that Sony itself is a member of Japan Display, their next-generation PlayStation VR is likely to be equipped with two such display panels. Japan Display said that the panel will ship at t

Since its launch, Android smartwatches have not performed well. Therefore, Google recently decided to re-build Android Wear as Wear OS, and hope it will occupy a place in the wearable, Apple and Samsung dominated markets. In order to achieve this goal, rebuilding the brand is a necessary step. The current situation is that almost every Android smart watch supports pairing with the iPhone, so Google decided to remove the Android name. Of course, rebranding is one thing, and reinventing it is another matter. Google is a leading company in the field of fashion technology, which helps it realize its vision. But there is one more thing that will be a hindrance to Google, that is to support the technology of Wear OS operation. At present, most Android smart watches still use the Snapdragon Wear 2100 chip that was introduced by Qualcomm in 2016. This chip has been transformed from the Snapdragon 400 on smartphones. Its performance has fallen behind the times, and an urgent replacement is n

In the global image sensor market, the gap between Samsung and Sony continues to shrink. Due to the popularity of smartphones and security products, the market for image sensors has grown rapidly. IC Insights pointed out in the report that the annual revenue of CMOS image sensors will increase to 13.7 billion US dollars by 2018, a 10% increase over 2017. By 2022, this figure will rise to 19 billion US dollars. CMOS sensors are constantly advancing, such as being able to handle a wide range of light intensities, speeding up imaging, increasing resolution, and adding more features to accomplish specific tasks. We have incorporated CMOS sensors into security video cameras, or robots and automobiles. Increase machine vision capabilities to identify people for gesture interfaces, VR/AR, and medical systems. In the new smart phones, the CMOS image sensor market is also growing, because many mobile phones install dual camera systems to enhance camera capabilities. In the global CMOS sens

Apple, Amazon, and Google are the three largest technology giants in Silicon Valley in the US with market capitalization of 858 billion U.S. dollars, 768.6 billion U.S. dollars, and 720.2 billion U.S. dollars. In particular, Amazon is experiencing rapid growth. It has successively caught up with Google and Microsoft to become the world’s second largest company. Second only to Apple, however, some analysts on Wall Street even said that Amazon will be earlier than Apple and other companies, becoming the first company whose market value exceeds 1 trillion US dollars. Artificial Intelligence Strategy In the past year, Google, Amazon, and Microsoft have soared in market value, thanks to artificial intelligence strategies. Among Internet companies, Google is taking the lead in developing artificial intelligence and transforming in this direction. Globally, Google’s AI technology is the most powerful. It not only uses AI technology to improve existing Internet products and services, but

This year, a "number one player" has spread all over the world, and this movie, which is displayed with almost animated content, has resonated with the global audience. Steven Allan Spielberg created an oasis as a virtual world with his imagination. In reality, maybe we still have a long way to go from such a game, but the VR headlines in the video can cause us enough attention. Take this opportunity, perhaps the VR industry can fight a turnaround. However, as far as the VR head-mounted devices I have experienced, the first is not to say that there are matching costumes that can have a somatosensory feature in the movies. Even the treadmills that can squat and squat 360° are almost impossible to achieve. Therefore, we had no choice but to expect that the current VR device could make a breakthrough in experience, but the current VR head display is not a problem with the way of wearing, or the resolution of the screen is still a play. Not long ago, the author experienced a
