Shanghai, 2021 / US Department of Shanghai / – 2021 Shanghai International Auto Show, chasing science and technology Wang Jianxin accepted an interview from a science, talked to the control of the “Cosmic First” The story, tells the story behind the “The First”. The content below is the original interview with the media:
Shanghai International Auto Show, chasing technology held a new product launch conference for the L3 automatic driving landing. At the press conference, the training technology issued two software products that have been built in two years: low-speed automatic driving (AVP) systems and parking space map navigation products, and three hardware products: single Ti TDA4 L2 AVP controller, The controller L2 +-level AVP controller based on two horizontal line journey 3 and the L3 full-speed domain controller based on three Ti TDA4. At the press conference, the scientific and technological declared that a product was “the first” universe. What does the “universe first” controller grow? With this curiosity, the reporter went into the booth.
Stepping into the booth, a small Lego model car placed in the center of the show, placed next to it With a silver controller, there is one laser radar on the rightmost side. There are many people on the scene. What product is, what is the black technology, the reporter interviewed Wang Jianxin, the software manager of chasing technology, let him answer us.

123] Q: Manager Wang Manager, can you introduce me that this Demo, which is chasing technology shows us what features?
Wang Jianxin: This controller of this demo is a single Ti TDA4-based ADAS controller based on self-developing. On the left of the Lego truck, we installed 6 cameras, and the 6 cameras could be input to this controller. On the right is a laser radar of the big street. Above the screen is showing the 5-way camera and all the way to the controller, the target detection result of live real-time live.

Q: This Demo, which is chasing show, is it called “universe first” product?
Wang Jianxin: Yes. Our Demo actually wants to show you the hardware and software strength of the training technology. Don’t see this controller is so small, it is already a volume of mass production testing. Moreover, use our software capabilities to play the power of the TDA4 chip to the ultimate, and can implement the 6-way study model and run when it is truthfully.
First: We simultaneously support the 5-way two million pixel car camera simultaneously input, and the input of a laser radar. The company can do this in the industry almost no.
Second: There is a deep learning network behind each camera. There is still a deep learning network behind the laser radar, that is, our industry’s first, run 5 target detection and 1 laser radar point Cloud multi-mode neural network. This is very difficult, other companies can only support a deep learning network, multiple cameras use this unique network, and we can support 6 deep learning networks.
This has not yet ended. At the same time, our software is still behind, support the original video record of the 5th camera.
The above 3 points, showers that our software is in our TDA4 controller, with both performance and stability to international leadership. This demo we think is the level of the “universe”. In fact, the “universe first” is a stalk in our conference. If you are interested in this tyranny, you can see the playback of our conference.
Q: Why is the software capabilities that chase, what is the advantage?
Wang Jianxin: The reason why we can do chips is because they have produced hundreds of pre-projects. We are a team that is stronger and fighting. At present, all car chips at home and abroad, whether TI, Renesas, NXP, Yingda, we have produced rich development experience.
At present, the underlying architecture of various chip mills in the automotive industry is different, and the combination of software and hardware must be done, relies on the maturity of chip manufacturers and support for partners. However, because of the limited human resources of the chip factory, all chip development manufacturers cannot be effectively supported, so if there is a corresponding development and mass production experience is an important factor in the combination of hardware and software. And as I mentioned, we chasing science and technology adapted to almost all the chips in China, so we only need to support the original chip of the chip, you can develop independently.
On the other hand, is there a efficient system design. We can perform the most reasonable development, deployment, optimization, and management of different chips, based on different chip features, in different processing units, to make full use of chips.
Finally, we have the global leading algorithm for multi-sensor integration, decision, planning, and deep learning. We take into account the cooperation and mass production of hardware, we directly use C language. Write, the highest running efficiency, and directly access hardware, which make our software and algorithms can be quickly, efficient and stable in landing production. 
Q: In the choice of chips, there are many different chips on the market. What is the trend of this aspect, why will we choose TDA4?
Wang Jianxin: About market trends, we see that the two-polarization is very serious. We see a type of new forces such as Tesla and Xiaopeng, advocate the hardware. Pursue super high force, or use a plurality of high algorithm chips to spell a 1000T super controller, or like Tesla from R & D chips. However, this type of route is that the complexity of the entire system is very high, and it takes a long time from hardware to software. It takes a huge cost.
The other extreme is, for those who can mass-produced large quantities in the next three years, such as TDA4, Gao Tong, the horizon J3, only more than a dozen T. Although this type of pattern has been launched, it is time, but the number of companies that truly do hardware software can be opened in China has only one bit number. And even the hardware underlayer is drivenMove, you can completely transplant the automatic driving function above it. Traditional Tire1 Only manufacturing capabilities, only algorithm companies, is there in embedded development and graft ability.
We chased a team with both hardware capabilities and software capabilities. We really can make our innovation algorithms and software to install a quantity-embedded team.
At the 2020 Beijing Auto Show, we have successfully demonstrated the automatic valetic parking system based on the Skyline J3 chip. At the same time, in the Guangzhou Auto Show of the same year, Forem. This Shanghai Auto Show, we show new developed, TDA4-based solutions are hardware and software products.

Q: The whole industry is now saying software definition cars, you can talk about your views on software definitions?
Wang Jianxin: In the field of IT, there is a saying that “all things you can say is software definition”, this concept has always been, but it is only hot in the car in recent years.
In this process, there is a very important variable, which has made many advances in the verge of hardware. So we can only change the software, you can give the same device multiple functions, and even have an unprecedented new feature.
However, I don’t think that the software does not blindly think that the software is omnipotent, because there is another sentence in the IT industry: hardware is the load of the software, the software that is separated from the hardware, is the air building Pavilion, there is no way Effect and role in real world.
So, software defining a car must be a hardware and software combination to achieve algorithm and efficiency, and achieve 1000 times of our we want.
This is also why we chasing technology software development will consider hardware and consider the cause of the chip in the initial top design. As a software, we are the application of algorithm, the following is the hardware of landing, which requires us to fully understand and resolve, system architecture, hardware architecture, Network architecture, thereby achieving system functions.
Software architecture, after more than 10 years of iteration and mass production on different chips, to today, can do, support multi-sensor input, modularity, deployment, multi-core transplantation, and communication, Maximum efficient use of hardware’s power resources.
is also because of these strengths, we can stand out in numerous software companies, in the shortest time, with the least amount of force, and provide the most, optimal automatic driving function.
Q: Thank you for your manager, and finally understand, what is the planning of future plans? 
Wang Jianxin: Our plan is very clear from everyone on April 19th release. We are a small company with a full stack of solutions in the industry, our goal is to become a supplier of China’s largest automatic landing product in 2025.
The automatic driving floor must be gradually carried out, and the way to chase the L3-level automatic driving is: low speed auxiliaries, high-speed alternatives. So in the past two years, we mainly drive a low-speed automatic driving.
From this year, we began to solve urban traffic congestion. The problem of gradually solving high speed and loop gradually. On the floor-to-ceiling chip, we now ask us to land on single TDA4, Dual Skyline J3 and Three TDA4. In addition, we are also working with NVIDIA to prepare for the application based on ORIN and ATLAN applications.
