Electronic core smell morning newspaper: Intel's big move, Xiaolong 820 was exposed

Today's core language

From the official PPT of MediaTek exposed by foreign media, MediaTek detailed the specifications of Helio X20 and Qualcomm MSM8996 (Zhenlong 820), so that we know the specific parameters. PPT shows that the Snapdragon 820 is a quad-core design with two 2.2GHz Kryo cores and two 1.7GHz Kryo cores. It is an alternative "size and size" architecture. Because it is exposed by competitors, the parameters of Xiaolong 820 in the picture are not necessarily true, but they do have certain reference value. For more information on technology, please pay attention to the daily electronic core morning newspaper.

First, the semiconductor

1, Intel's big action exposure: the acquisition of CDMA patents. The Taiwan media has confirmed that Intel will spend 7.5 billion to 8 billion NT dollars to acquire VIA's mobile phone chip factory, Wei Rui, and Intel is doing CDMA2000 patent technology. The news mentioned that the acquisition of Intel and VIA Telecom has been basically settled. Later this month, the two parties will officially announce the incident, and the acquisition will not affect the previous 7 billion 13 billion signed by Weirui and MediaTek. Yuan patent authorization. The report also mentioned that because VIA has been losing money in recent years, selling VIA Telecom to fill losses is also a no-brainer. For this acquisition, the Secretary-General of the Mobile China Alliance, said that it is important for chip suppliers to provide full-scale, just as Intel can get into the iPhone if it doesn't have CDMA.

2, Xiaolong 820 exposure! MediaTek sold it. . . Very unexpected, Qualcomm Xiaolong 820 actually exposed this form, it appeared in MediaTek's official PPT. From the official PPT of MediaTek exposed by foreign media, MediaTek detailed the specifications of Helio X20 and Qualcomm MSM8996 (Zhenlong 820), so that we know the specific parameters. PPT shows that the Snapdragon 820 is a quad-core design with two 2.2GHz Kryo cores and two 1.7GHz Kryo cores. It is an alternative "size and size" architecture. Its built-in GPU is the Adreno 530 with a frequency of 650MHz. Other specifications include displays that support up to 28 megapixel cameras, 4K 60 Hz video decoding, 4K 30 Hz video encoding, and up to 4K resolution. Of course, the baseband is still full Netcom and supports LTE Cat.10. Because it is exposed by competitors, the parameters of Xiaolong 820 in the picture are not necessarily true, but they do have certain reference value.

Second, communication news

1, 300Mbps Telecom LTE-A is coming! Although many domestic manufacturers have claimed that their products support LTE Cat.6 or even Cat.9 when they release their mobile phones, it is regrettable that the current 4G networks of the three major operators in China are still LTE Cat.4, so that the baseband is no better. The phone can't play. Now, the good news is coming. Today, China Telecom Guangdong announced that it will launch LTE-A commercial trials in Guangzhou and Shenzhen on May 17th, and LTE Cat.6 is very close to us. We don't explain much about the technical principle. Just remember that it can increase the network speed by means of carrier aggregation. According to the pictures provided by Keke.com, the measured download rate of telecom LTE-A at the conference site reached 224.98 Mbps, and the upload rate reached 64.76 Mbps, which is much faster than the current peak speed of 150 and bps.

Third, automotive electronics

1. The key car system has security holes and is more easily stolen. People are curious and embarrassed about the shape of smart cars. They may use fully automated driving, equipped with advanced in-car AI systems, and seamlessly synchronize data with mobile devices to completely change the driving experience. Now, the smart car experience that you can easily achieve is probably a hands-free, keyless start-up system that allows users to automatically unlock the car as they approach the car via a mobile device and pairing key. However, such systems have serious loopholes that make car thieves more likely to steal cars. According to Forbes, the British police have issued a warning to remind owners of car owners with keyless starters that hackers may steal cars more easily.

2, the fault is not oneself: Google disclosed the driverless car accident. According to foreign media reports, Google just admitted this week that their driverless cars have been tested for 11 small traffic accidents in the past six years. However, Google’s driverless project director Chris Urmson explained the cause of the accident by blaming other human drivers for the main responsibility. According to anonymous insiders, four accidents occurred in California, two of which occurred in driverless mode, and two occurred during human driver control. In theory, driverless cars should be safer than traditional cars. Because these vehicles are equipped with a large number of cameras and sensors, the computer reacts faster to human drivers in special situations. Even when an impending collision is detected, the driverless car will take safety measures such as tightening the seat belt, avoiding, honking the horn, etc. to reduce the damage caused by the collision or warn the drivers of other vehicles.

Fourth, virtual reality

1. Korean media: Samsung hopes to cooperate with Microsoft to develop HoloLens. In January, Microsoft released HoloLens, a reality-enhanced device that displays interactive holograms. In addition, HoloLens will support running Windows 10 apps, which have so far looked great. According to the Korea Times, Samsung also hopes to cooperate with Microsoft to develop HoloLens. Sources revealed to the media that Samsung has been looking for new manufacturing innovations (ie, groundbreaking products) and HoloLens is a key technology for healthcare and medical devices. Do you think Microsoft should work with Samsung to develop HoloLens?

Five, intelligent hardware

1, Sony launched Xperia A4: 4.6-inch screen + Xiaolong 801. Recently, Sony launched the new mobile phone Xperia A4 for the Japanese operator NTT DoCoMo. The model of the machine is "SO-04G". If there is an international version in the future, it should be the rumored Xperia Z4 Compact. The Xperia A4 features a 4.6-inch 720P display and supports X-Reality display technology. It is powered by a 2.5GHz Snapdragon 801 processor with 2GB of running memory and 16GB of storage (expandable). The front camera has 2.2 megapixels (recordable 720P video) ), the rear camera is 20.7 million pixels, with 1/2.3 inch sensor size and f2.0 aperture Sony G lens, support 120fps slow video recording, HDR and 1080p video shooting and other functions, running Android 5.0 operating system.

2, the minimum is less than 2 inches, the mini computer dedicated display. The Raspberry Pi mini computer is already very powerful. Is there any way to make it stronger? Add a monitor! So PaPiRus is here. PaPiRus is a display specifically for the Raspberry Pi, which is only 1.44 inches, 2 inches and 2.7 inches. It is very mini. PaPiRus uses an electronic ink screen, and perhaps the display is not so bright, but it is better than energy saving. The installation of this mini-display is very simple, because it is tailor-made for the Raspberry Pi, and even after the connection is not needed, boot. Perhaps the Raspberry Pi with this monitor can't handle any complicated work, but it's more than enough to act as an information display.

Six, robot

1. Cobos and Alibaba Cloud Pushing Robot: Customizable and clean. On May 13th, Cobos Robots joined Alibaba Cloud yesterday to launch the sweeping robot "Dabao blossoming". According to reports, the addition of Alibaba Cloud Data Platform has realized remote control and custom cleaning of sweeping robots. According to the data, Cobos Robotics was founded in 1998 and is one of the largest home service robot manufacturers in China. The product line covers six robot categories such as sweeping, window cleaning, shopping guide, air purification, and parent-child interaction. The biggest feature of the sweeping robot released this time is its "Blue Whale Cleaning System". According to reports, this cleaning system for simulating the blue whale predation process can achieve the cleaning of the floor, carpet and the simultaneous drying of the wet and dry rag.

2. Experts say that robots cannot rule the world because energy consumption is too high. On May 14th, according to foreign media reports, if you are still afraid that robots will rule the world, then this news may give you peace of mind. Some experts say that today's robots are so energy-intensive that they cannot take over the world. The US Department of Defense's Advanced Research Projects Agency (DARPA) will host a robotics competition next month to discover robotics that may be used in disasters over the next 10 years. Gill Pratt, the organizer of the competition and project director of the Advanced Research Projects Agency, said that even fairly advanced robots can't assess the surrounding environment well, and they can't work when the power is exhausted. Big problem.

USB4 Cable

USB4 specifies tunneling of:

USB 3.2 ("Enhanced Superspeed") Tunneling
DisplayPort 1.4a -based Tunneling
PCI Express (PCIe)-based Tunneling


Main Benefits of USB 4
The new USB 4 standard has three main benefits over prior versions of USB.

40 Gbps Maximum Speed: By using two-lane cables, devices are able to operate at up to 40 Gbps, the same speed as Thunderbolt 3. The data is transmitted in two sets of four bidirectional lanes.


DisplayPort Alt Mode 2.0: USB 4 supports DisplayPort 2.0 over its alternative mode. DisplayPort 2.0 can support 8K resolution at 60 Hz with HDR10 color. DisplayPort 2.0 can use up to 80 Gbps, which is double the amount available to USB data, because it sends all the data in one direction (to the monitor) and can thus use all eight data lanes at once.


Compatible with Thunderbolt 3 devices: Some, but not necessarily all USB 4 implementations will also work with Thunderbolt 3 devices.

Better Resource Allocation for Video, PCIe: In lieu of alternative mode where the other interface takes over the connection, USB 4 devices can use a process called "protocol tunneling" that sends DisplayPort, PCIe and USB packets at the same time while allocating bandwidth accordingly.
