Mobileye Puts Lidar on a Chip—and Helps Map Intel's Future

preview

There have been bright spots as well, though, including one announced today: Mobileye, the self-driving car company that , has put lidar on a chip.Mobileye is not alone in its pursuit of shrinking down in both size and cost; companies like Aeva and Voyant Photonics have developed their own systems as well. Mobileye CEO Amnon Shashua doesn’t expect his lidar system-on-a-chip to be fully baked until 2025. But it’s the kind of breakthrough that will help the company retain its tight grip on the assisted driving technology market, with the potential to dramatically drive down the cost of the sensors that will help enable full autonomy. As part of Intel, Mobileye can tap into manufacturing resources few can match, not only to produce the chips on schedule but at scale. More importantly, the lidar SoC is emblematic of Intel’s way forward: looking beyond the CPU.Chip Shot&nbsp;Start with the lidar SoC itself, which Shashua announced today during the CES technology trade show. Lidar systems use lasers to determine the location of objects. About the size of a Triscuit, Mobileye’s prototype integrates those lasers onto the chip itself through a process called silicon photonics. And rather than using time-of-flight—which sends out bursts discrete pulses of light and measures how long it takes that pulse to return to the sensor—Mobileye’s solution relies on so-called frequency modulated continuous wave technology, which instead sends out a constant stream of light. FMCW systems can calculate both the range and velocity of objects, which makes it more effective than time-of-flight.“You will be able to see hazards on the road from 200 meters away versus 100 meters away,” Shashua says. “The fact that you have velocity data at every point, this 4D measurement also gives you a huge advantage in terms of fidelity of data and what you can do with it. You can do better class terrain, you can get the heading of targets instantaneously.”Most PopularSilicon photonics is itself not a new method of manufacturing chips; Intel has previously used the technology in data center transceivers. But lidar is a natural fit, given that it relies on lasers in the first place. It’s certainly an improvement over the bulkier, more costly systems used today.“The advantage that silicon photonics can bring is a small form factor solution, which can result in a compact size of the device in the car at the end,” says Kiyoul Yang, a postdoctoral researcher at Stanford University who focuses on photonic hardware. Many companies today use a lidar system based on rotating mirrors, Yang says, which requires the manufacture of discrete, expensive components. “If everything can be integrated in a chip in a small form factor, then everything can be produced with a low cost,” he says.Check out the and kick off the new year in tech with .Again, Mobileye is not the only company banking on FMCW, or lidar chips more broadly. But it does have a distinct advantage in that Intel already has a silicon photonics manufacturing facility up and running in New Mexico. “Being able to build an FMCW lidar requires know-how, but also if you don’t have the special fabs to create the lidar on a chip, it becomes too expensive. It become unwieldy,” says Shashua. He expects the cost of each lidar SoC to be in the hundreds of dollars each, orders of magnitude cheaper than what systems cost today.Even if Mobileye’s production roadmap holds steady, a uncertain regulatory outlook could slow its timeline. Still, it’s making nearer-term progress as well, announcing at CES today that it would expand its autonomous vehicle testing to Detroit, Paris, Tokyo, and Shanghai in 2020. (The locations are strategic; each is near a car manufacturer that Mobileye supplies self-driving technologies for.) And it has used the millions of cars with Mobileye onboard to crowdsource a map of almost 1 billion kilometers of the world’s roads to date, processing 8 million kilometers every single day. For all the attention Tesla gets, Mobileye is by far the market share leader in the autonomous driving space.That reputation, and Intel’s deep pockets, will help it against smaller competitors in the lidar SoC race. “I’m a big believer that in the auto industry, trustworthiness is a big differentiator,” says Mike Ramsey, an automotive analyst at Gartner. “Can I trust this vendor to deliver on time, to deliver in quality? And Intel has the very important feature of being a very large throat to choke if something goes wrong. Don’t underestimate the value in that.”Mobileye makes up a small percentage of Intel’s revenue overall. But along with the client computing group—that is, the chips that go into PC and adjacent products—it’s the only segment that grew in the company’s most recent quarter. It’s exactly the kind of new territory that Intel needs to stake out aggressively to avoid another smartphone-style miss.“If you look long-term, a company like Intel needs to look for new growth domains. It’s not easy to find one. You want to look for a new market that is the size of hundreds of billions of dollars,” says Shashua, as well as one that leverages Intel’s strengths. “Those domains are rare. We are in that domain.”XPU Marks the SpotMobileye’s lidar SoC is the sharpest example of what Intel calls its “XPU” strategy—that is, looking beyond the CPU to computing in all of its many forms. The company launched its first discrete graphics card last fall, has a dominant position in data center processors, and in 2019 acquired AI chipmaker Habana Labs, which a few weeks ago won business from Amazon Web Services to use its accelerators to train deep learning models.“At our heart we’re a computing company,” says Gregory Bryant, who leads Intel’s client computing group. “We see this world where more and more things need computing, more and more things look like a computer, not just the server or the PC but the automobile, the home, the factory, the hospital. All those things need computing, and need intelligence.”Most PopularThat broadening out comes at a time when Intel faces more challenges than ever to its traditional business lines. Manufacturing delays have kept it stuck on a 10-nanometer process for fabricating its chips, while competitors have moved on to smaller forms. The company’s chief engineering officer, Murthy Renduchintala, left last summer. And the hedge fund Third Point issued a scorching public letter in late December, calling on Intel to “retain a reputable investment advisor to evaluate strategic alternatives, including whether Intel should remain an integrated device manufacturer and the potential divestment of certain failed acquisitions.”Intel has already taken steps to shed some businesses, selling its NAND flash memory business to South Korean semiconductor company SK Hynix last year for $9 billion, and its smartphone modem business to Apple the year before that. It has even explored of some of its high-end chips to Taiwanese rival TMSC, which would be a dramatic departure for a company built largely on fabs.“Certainly we’re not where we want to be in the recent past, and we’ve taken steps to improve,” says Bryant. “We need to execute better,” But Bryant also notes that thanks transistor breakthroughs like the company’s SuperFIN architecture, the company has steadily improved its processor performance despite by stuck on 10nm. And it’s banking on task-specific products—it rolled out distinct chips for business, education, and gaming at CES as well—to stay competitive.As for Apple, the M1 chip is a scorcher, thanks in part to Cupertion’s fully integrated design process. Bryant points to Intel’s Evo and Vpro platforms, in which the silicon giant works closely with laptop manufacturers to guarantee certain specs like long battery life and faster wakeup times. “I take the competition very seriously,” says Bryant. “They’re a very capable competitor. But I think we need to play to our strengths around real-word performance, around choice, around the different segments that we serve, around optimizing for different workloads.”But while Intel continues to find ways to compensate for its current manufacturing lag, acquisitions like Mobileye and Habana Labs have helped it diversify for the future. “They’ve broadened the aperture very widely,” says Patrick Moorhead, founder of Moor Insights &amp; Strategy.The problems Intel does have can’t be solved by putting lidar on a chip. But the announcement is indicative of what the company does need to move forward: A roadmap that’s multi-dimensional.More From WIRED on CES 2021 is Executive Editor, News at WIRED, overseeing day to day coverage across the site.
