Rush into the automotive electronics market MediaTek aimed at radar and visual SoC

Taiwanese smartphone chip maker MediaTek, in its high-performance, low-power application processor expertise will help car manufacturers and first-line industry to develop advanced digital cockpit system faith convincing, is a drill Into the growing automotive electronics market.

MediaTek and Qualcomm have the same smart phone application processor technology advantage, so that the background of the two companies to actively arm the military electronics market. Qualcomm, through the acquisition of NXP Semiconductors to expose its plans for the market to throw a shock bomb. The MediaTek is to choose a more organic approach, but also is facing a tough battle. MediaTek's ambition to enter the automotive market is easy to understand, but the car with the market's success will still need to wait and see. mg300j2ys50

At this year's International Consumer Electronics Show (CES), JC Hsu, General Manager of MediaTek's new business development division, introduced the company's layout in the automotive electronics industry. Xu Jingquan stressed in the interview that the strength of MediaTek is not only telematics and multimedia technology, the secret weapon of winning other 77-79GH millimeter wave (mmW) radar, advanced driving support system (ADAS) camera and ultra-low power Of the visual SoC technology.

Of course, Qualcomm later in the year to complete NXP's acquisition plan, is expected to be a sharp lead in the automotive electronics, MediaTek will also face a severe test. The face of the upcoming challenges, Xu Jingquan all do not worry. "Our customers in every field are industry leaders, including radar, video cameras and visual SoCs," he stressed.

MediaTek intends to take advantage of the processor, high integration SoC, modems and RF and multimedia technology advantages into the automotive electronics market

CMOS radar single chip

According to market research agency IHS Markit Automotive research report, radar technology is to enhance the performance of ADAS system, the most commonly used sensor technology, is expected in 2021 radar sensor market will grow to more than 50 million sets Of the scale. fp50r12ks4c

"The experience of MediaTek in 802.11ad technology, which operates in the 60GHz band of unlicensed, multi-gigabit wireless transmission technology, and the associated IP developed with IBM, will come in handy when developing radar chips," he said. . "

The disadvantage of using the 60-GHz band is that the signal can not penetrate the solid material and can therefore only be restricted to a separate room. Thus, IBM and MediaTek will use the military phase array radar technology microfilm into a single chip, so that 60GHz transmitter can bypass the obstacle to send signals to the indoor receiver, improve the signal can not penetrate the solid transmission problem. Xu Jingquan explained: "Today, we use a similar technology IP R & D vehicle radar chip."

As the cost is too high, MediaTek's radar chip will not use silicon germanium (SiGe), but the introduction of CMOS single-chip SoC, is expected to be the first half of this year can be kind. The benefits of single-chip integration can be reduced BOM cost and radar power consumption.

Xu Jingquan said that its short-range single-chip SoC power consumption will be less than 2W, while supporting medium-distance transmission (about 80 meters) of single-chip, power consumption is only 2-3W. "Therefore, we are currently working closely with a first-tier manufacturers."

Radar Technology Controversy

Of course, MediaTek in radar technology there are many places to work hard, especially in the face of Infineon Technologies (Infineon Technologies) and NXP, the two industry leaders.

Infineon has pointed out that the company just in 2016 had already sold 10 million radar chips, in addition, accumulated in 2015 before the chip sales reached 10 million, the data can clearly see the radar technology In the past year's car market is how red.

Infineon's current radar chip uses silicon germanium (SiGe), while the use of CMOS technology version is currently being developed. NXP launched at the beginning of this year's CES known as "the world's smallest, with ultra-high resolution 77GHz radar transceiver single-chip (7.5x7.5mm)".

Hella, a first-tier automotive radar company with more than 15 years of experience in automotive radar, showed at NXP's booth that the company will launch Compact Radar in 2018 with NXP's RF CMOS technology.

Compact Radar will be used for short-range and medium-distance transmission applications, Hella original equipment, global marketing manager Kristian Doescher said: "We have completed the field test, preliminary results Hao show great prospects.RF CMOS technology allows us to Product size reduction. "

Visual SoC: HOG and CNN

In the field of visual SoCs, Israel's Mobileye has a leading position in the automotive vision chip market. The EyeQ chip developed by the company is also the gold standard for other companies to design, and it is not easy for the latecomers to contend with it. .

However, Xu Jingquan see this in the MediaTek opportunities. More and more automotive OEMs are now looking for a more resilient architecture when developing visual SoCs. "Some OEMs need more sophisticated image sensor related technologies to implement their sensor fusion in order to add their own algorithms."

"Our chips will support two image processing technologies - one that focuses on traditional computer vision algorithms, such as the" Directional Gradient Histogram "(HOG), and the other on the visual SoC, which is currently being developed by MediaTek. One is focused on deep learning based on convolutional neural network (CNN) technology, and MediaTek also plans to add special local memory to the SoC to support neural networks. The visual SoC will sample in early 2018.

But why add the same computer vision and depth-of-learning technology to the same chip at the same time? "Deep learning technology can not solve every problem, and we are currently working with first-line customers to develop two technologies to meet their deeper system design needs," said Xu.

Android system into the car system

Xu Jingquan pointed out that more and more emerging market, car manufacturers began to support the Android car infotainment system (IVI) interested in "they want to make good use of smart phones and tablet computers have been established for the existing ecosystem.

However, when asked about the Android application fragmented differences for the automotive electronics industry may bring adverse effects, Xu Jingquan confessed that there will be some worry.

MediaTek from 2014 to develop automotive electronics market-related technologies. "We currently have more than 100 employees in the automotive electronics sector - most of them engineers and some business people," says Xu.
