ADI inertial navigation chip has been applied in the automatic driving system GNSS / INS system, excellent performance, from tactical level down to automotive applications. With the development of autonomous driving technology, ADI sensor technology in In the process of cooperation with upstream and downstream manufacturers, it will be iteratively updated, which will become more and more suitable for the automatic driving production level.
Reporter: Some autopilot companies choose to enter L4 directly, while others start from L1 and perform iterative upgrades of L2-L3-L4. Which route do you prefer? Why?
Jerry Cui: All roads lead to Rome. The choice of route is based on the current situation of the company. Traditional car manufacturers prefer iteration because there will be new models coming out. Startups tend to go directly to L4 and take advantage of algorithms. Manufacturers of different routes, in the process of exploration, are more cooperative. ADI has also been cooperating with various companies of ecosystem to jointly develop solutions and explore technical routes and product directions. (Proofreading/叨叨)
2. Scientists demonstrate storage technology with a storage density of several thousand times that of solid state drives;
According to a study published in the journal Nature Communications, Alberta University scientists demonstrated a new data storage technology that uses a single hydrogen atom to store 0 and 1, with a storage density thousands of times higher than mechanical hard drives and solid state drives, and hundreds of times more Blu-ray discs. But it may take at least five years for this technology to become practical.
Hydrogen atoms are only 0.5 nanometers in diameter, so the new technology's data storage density can reach an astonishing 1.1 petabits per square inch (138 terabytes). By contrast, the same area Blu-ray disc can only store 12 terabits of data, while traditional machinery And SSDs have a storage density of 1.5 terabits per square inch.
According to Roshan Achal, the lead author of the paper, 45 million songs in the entire iTunes library can be stored on the surface of a coin with a denomination of $0.25.
3. Qualcomm said that there are solutions to solve the power consumption problem of dual-screen devices;
We already know that Microsoft is developing a folding device code-named Andromeda, but it seems that Qualcomm is also interested in supporting dual-screen Windows 10 PCs, although there are currently no specific products to share. Miguel Nunes, Senior Director of Product Management at Qualcomm, accepts In an interview, Qualcomm is preparing a solution to solve the power problem of dual-screen devices driven by Microsoft Windows 10 operating system.
Miguel Nunes said that Qualcomm is developing a lot of cool content, but he did not directly admit that the ARM-driven Windows 10 dual-screen phone is in the middle.
'You will see the change in form factor. One of Qualcomm's advantages for the industry is the ability to integrate. If you look at the Snapdragon 835/850 platform compared to the Intel 'X86' processor, we look at it from a design perspective. Look at 30 times smaller. So, you can imagine that if you reduce the design by 30%, we can start using the form factor to do a lot of interesting things. I think you will see the shape and future innovation... dual screen and Various form factors, because we can achieve this, 'Miguel Nunes, senior director of product management at Qualcomm, said in a statement.
Not only is Microsoft prototyping folding PCs, but other original equipment manufacturers have been using them to inspire their devices. Earlier this year, Asus showed off its dual-screen laptop, and Lenovo also showed something similar. Equipment. cnBeta
4.MLCC raises the eyebrows and assembles the foundry to become the biggest victim and sandwich biscuit
The price increase of MLCC is expected to continue until 2019. The Taiwanese factory seems to face a nightmare that will not wake up. Because of the low gross profit margin, the products with slow growth will not be able to withstand the impact of price increases, and the market price will not be available. "Purchasing, can only see the car electronics, emerging technology products, into the MLCC and other factories priority supply targets, the foundry has become the biggest victims of price increases and sandwich biscuits.
After the DRAM price increase in the past year, the MLCC price increase trend continued to exceed expectations, causing a full impact on OEM assembly, industrial computers, and network operators.
Many companies have been affected by the increase in raw materials. The senior executives of the foundry have bluntly stated that they have stabilized the gross profit margin of “three to four” in the past. Now they can only be “guarantee one team”, the raw materials are rising, and the gross profit margin is falling into operation. Puzzle.
Although large factories can use the long-term contract to request stable supply of MLCC plants, and even call for price increases to customers, the problem is that many products have entered a cycle of slowing growth, unable to withstand price increases, and the supply chain is to guarantee quality and future orders. Can only bitter the cost of price increases, into the biggest victims of the price increase and sandwich biscuits.
The MLCC, which has only increased its price once in 20 years, is where the actual demand is. The high-level representative of the factory said that the MLCC spot market actually has it, but the price is more than 10 times higher. Some MLCCs are used for vehicles, emerging technologies, etc. The owner's limited gross profit margin, so the offer price is not good, and finally caused "difficulty in supply."
