In recent years, automatic driving quickly from the ideal to reality, set off a new round of the automotive industry technological change wave. It is understood that the past seven years, the new automatic driving technology patents up to 5839. And from the future development trend, IHS survey shows that automatic driving car will be between 2020 to 2040 to 63% growth rate. And the resulting large amount of data will continue to expand, which the car storage and fast computing power put forward higher requirements.
Automotive Optical and Storage Market Leader Micron has pointed out that by 2020, storage needs in the Internet car may reach 1 trillion bytes, to drive full automatic driving need to have 300 gigabytes per second (GB / s) above the storage system bandwidth. To this end, how to meet the intelligent network of large data storage era and the need to ensure the safety of the network to become the key to the industry to explore.
Where does the massive data come from?
Overall, the automotive industry's storage data is mainly from the infotainment system, dashboard, ADAS system, communication and power system five aspects, and with the gradual escalation of automatic driving, ADAS system, infotainment system, the rapid increase in the amount of data Spawned a larger space for car storage.
With the diversification of consumer upgrades and demand, car infotainment system involved in the content and digital functions continue to enlarge, in addition to navigation, but also covers the fault detection, vehicle information, body control, mobile office, wireless communications, car interconnection, Based on the online entertainment features and TSP services and other applications, all applications in the occupants to bring unprecedented sensory enjoyment and information needs, but also bring a huge amount of data. Once the application process of data storage problems, no less than the phone card, the computer crash depressed.
The rapid development of the driving support system (ADAS), so that the vehicle has a 360 ° look around, automatic parking, emergency braking and many other features. According to this development trend, the camera, the radar will gather more and more information, picture accuracy is getting higher and higher, if the car driving process, the system appears Caton or data instability on vehicle safety will be larger The hidden dangers. In addition, because the automotive intelligence continues to increase, the number of power system sensors increased, is bound to produce massive telemetry data. The integration of automotive instrumentation, the interior of the interior of the interior will continue to bring the amount of data rose.
From this point of view, the development of automotive storage technology directly affects the automatic car upgrade, and automatic driving in the promotion of automotive storage technology upgrades and market expansion at the same time also brought great challenges.
However, the autopilot car storage is divided into cloud storage and localized storage. To this end, in recent years there are views that cloud storage came, do not need to store the local car. "For autopilot, we can not upload it to the cloud even if we have 5G. We need to introduce artificial intelligence to determine which data is important and which data," says Doug Seven, head of the Microsoft Azure Car Networking Platform. Can be discarded and what needs to be uploaded at a convenient time instead of uploading in real time. "Mike Rayfield, senior vice president of Micron's Mobile Products Division, also points out that" connecting to the cloud can reduce local storage, but even if it's ubiquitous interconnection, Local storage, cloud storage and local storage there is a balance between the need for industry to study the control.
Smart interconnection makes the car a storage industry "potential shares"
From the following Micron data provided before we can see, with the recent automotive intelligent, the rapid development of the Internet, the new storage solutions to the application of the car cycle is getting shorter and shorter. It is understood that DDR2 products from the computer application to the car infotainment system took five years, and LPDDR4 from the smart phone to promote the car was less than two years time. To this end, the car has become a storage industry can not be ignored "corner", the major industry giants in this area has also increased efforts to develop.
At the recent World Conference on Mobile Communications (MWC Americas 2017), Micron officially unveiled its LPDDR4 on its next-generation driving assistance system ADAS and automotive infotainment system, which is four times the peak bandwidth of LPDDR2, LPDDR3 Twice the power consumption. It is worth mentioning that Micron is now shipping LPDDR4x to major chip partners, which runs at 4266 Mbps (MT / s) per second, which is the highest speed allowed by the LPDDR4 specification.
In addition, Micron also announced that it will provide high-bandwidth GDDR6 storage solutions for the automotive market. Graphics memory (GDDR) is a high-performance memory, Harvatek is currently widely used in games, graphics and virtual reality applications. Micron plans to take advantage of its graphics memory to provide the highest bandwidth solution to enable GDDR technology to meet Level 4 - fully automated or even higher level needs. The technology is expected to be available around 2018. Mike Rayfield pointed out that with the rapid development of automatic driving, LPDDR technology will soon upgrade to 5 generations, 6 generations, and 5 years after the bandwidth will also be expanded from the current 68GB / s to 448GB / s.
"I think the car is the next big customer base, Micron currently has about 40% of the market share in the future we will continue to force." Micron Embedded Products Division, said Jeff Bader, vice president. It is understood that shortly before this exhibition, Micron has expanded its investment in Taiwan, and the investment authorities have continued to cooperate with existing chip partners to assist in moving the consumer products from the mobile market. Relevant data show that 2017 car storage market size of about 22 billion US dollars or so. With the heating of autopilot technology, the future market outlook for storage systems is immeasurable.
The challenge of car storage - security
Mentioned the network security, read the "speed and passion 8" friends estimated that there will be a lingering fear, unmanned car once the network loopholes, the security issues will be fatal.
In the earliest, people are only crazy for driving themselves, and with a pile of network attacks such as the United States Fiat Chrysler because of hacker risk and large quantities of recall, BMW ConnectedDrive digital service system was invaded, network security experts through Tesla Model S existing loopholes to open the door and go away, but also to the Model S to send "suicide" command, etc., alert the major car prices began to automatically drive network security, information security issues on the agenda, and car storage information security natural Covering them.
For the defense of the car's storage in this area, Mr. Jeff Bader said in an interview with Gazette that Micron has now introduced security guidance for a fully based memory system that supports Authenta technology, which has led to the expansion of hardware-based Authenta ™ security The value of the solution. "In addition, Jeff Bader added," The company plans to provide the Authenta ™ hardware and software development kit to all automotive and Internet customers at the end of this year to begin evaluating how to integrate Authenta-enabled flash memory into its security architecture, Enabling secure startup, cloud-based authentication, authentication, and deployment capabilities. In this way, customers do not need to add additional hardware components in the design, you can improve the defense of its solution depth. "
Not only Micron, in this conference, Microsoft, Qualcomm, NVIDIA and other business representatives also expressed views on the safety of the car network, some of which enterprises have established cooperation in this area alliance. "In an increasingly complex and interconnected world, an organization collects, manages and analyzes, and uses data capabilities to effectively separate the winners from the runner-up." In an interview, an industry member has spoken such a sentence. And this sentence may be the future of the core of automatic driving competition, and car storage is only one of the ring, is also a crucial part.
