  Core Engine Technology is a company focusing on the field of automotive high computing power chips. High computing power chip is a prominent new application point in the process of automobile intellectualization, such as intelligent cockpit chip. The smart cockpit chip of Simeon can support multi-screen, multi-operating system and auxiliary driving to complete the multimedia and human-computer interaction of the entire smart cockpit.

  

  In addition, ADAS and SoC chips for autopilot have also become new application points. Our products include L3 and L4 autopilot chips for advanced intelligent driving. With the evolution of the entire body electrical architecture and the change of functions, we are also planning and launching the high computing power chip of the on-board central computer to achieve the support of computing power in the evolution of the body electrical architecture. The common point of these chips is that they have high computational power, which is not at the same level as the traditional light, wiper and window controller (ECU). In addition, there is no doubt about the reliability requirements of automobile chips, and compliance with ISO26262, AEC-Q100 and other vehicle-level requirements is also essential.

  

  In addition, these chips have several features. For information processing, whether it is body information processing, driver behavior, or the encryption and collection of surrounding environment information are all-around. In addition to the functional security we emphasize, information security is also essential to meet the security requirements of the State Security algorithm. In order to support the reliability of the high computing power chip, we have adopted the advanced 7nm technology, so that the computing power, power consumption and reliability of the entire chip, including the integration of many IPs, have been well optimized, and can provide users with products that take into account high computing power, high performance, low cost and high reliability.

  

  At the end of 2021, we successfully streamed the first 7nm smart cockpit SoC Core Dragon Eagle 1 in China. This year, we will carry a number of models to market, which will break the monopoly of overseas competitors for the first time in the field of smart cockpit.

  

  Core Engine Technology was established at the end of 2018, and the development of Longying 1 product began in the middle of 2019. The R&D and production of automobile chips are indeed challenging. After more than two years of development, the Dragon Eagle 1 was successfully released at the end of 2021, with the support of many domestic investment institutions.

  

  There is a certain difference between such high computing power chips and traditional automobile chips. A large part of the team members of Core Engine Technology have the background of server chips and automobile chips. The accumulation of high computing power, high concurrency and high bandwidth design architecture of server chips and the accumulation of reliability and security design of automobile chips are combined, enabling us to launch a 7nm high-resolution intelligent cockpit chip within two years.

  

  Trend analysis of computing power of 7nm high-performance smart car gauge chip

  

  The auto chip market has risen rapidly, and most of the growth has come from the opportunity points brought by auto intelligence. High computing power chips have achieved double-digit CAGR growth in smart cockpit and automatic driving. Many people will ask, what about the supply guarantee of advanced process and high computing power chips?

  This is the data of TSMC's 2021 financial report. The largest production capacity of TSMC's entire supply chain is 7nm and 5nm, and the fastest growing is also automotive chips. In addition to the core engine, many major international manufacturers have invested in this aspect in the advanced manufacturing process of automotive high-computing chips.

  

  Since 2018, the technology of smart cockpit chips and human-computer interaction chips on automobiles has begun to shift to advanced technology. So what kind of experience can 7nm bring to users in actual use? First of all, the more advanced the node technology is, the faster the transistor reversal speed is, which can lead to the improvement of the main screen performance. The second is the reduction of power consumption. With more advanced technology, the power consumption of logic circuits of the same size will be lower. In addition, advanced technology can increase the density of transistors, thus bringing cost optimization.

  

  After analyzing the traditional technology and the advanced technology of 16nm and 7nm, we decided to launch the domestic smart cockpit chip project on the 7nm node technology two years ago. In fact, whether for 7nm or 16nm, the biggest challenge lies in the fact that the design of VLSI requires a large number of resources and team members to carry out research and development for a period of 2 to 3 years. The real competitors facing the product are not the competitors in the market when the project is launched, but the prediction of the later stage of the market after crossing the research and development cycle.

  

  Core engine product introduction

  

  Dragon Eagle 1 can achieve 90K DMIPS CPU power and 900GFLOPS GPU power. For the use scenarios in the automotive environment, we use the hard isolation technology to fully open the computing power to customers.

  

  In recent years, some chip manufacturers have gradually shifted from mobile phones to the field of automobile cockpit. There is a big difference between the mobile phone and the cockpit. The mobile phone is one screen, while the car has multiple screens; There is one operating system on the mobile phone and multiple operating systems on the car; The mobile phone is started at high frequency and operated at low frequency. Most of them are in standby mode when the screen is off. As long as the car is started, the cabin system will keep running at full speed.

  

  According to the different operation scenarios and performance requirements of mobile phones and cars, we have done a lot of optimization for car applications at the design stage.

  

  The bigger difference between car chips and mobile phones is that cars have very high requirements for safety. For the functional safety requirements of the cabin, we have built in ASIL-D functional safety island, which supports safety communication and safety display, to ensure that the digital instrument panel, alarm sound and other high-security components can achieve real-time, reliable and safe without external interference.

  

  Today's intelligent cockpit is equivalent to an information collection center. In order to ensure the reliability and security of user information, we have joined the information security island, which not only supports international encryption algorithms, but also supports SM2, SM3, SM4 and other national encryption algorithms, meeting the requirements of national encryption algorithms, and supporting the security and confidentiality of communication and local data operations required by remote wake-up and other operations.

  

  In terms of quality, we have obtained the ISO9001 quality certificate and the certificate of compliance with AEC-Q100 vehicle specification level.

  

  With the passage of time, the display and rendering of images in the field of intelligent cockpit also put forward higher requirements for GPU computing power. With the popularization and application of the integration of cabin and driving and cabin and parking, the original auxiliary driving area and DMS functions are more and more integrated into the intelligent cockpit.

  

  As an upstream chip supplier, we are also making every effort to improve product performance. Faced with the opportunity of localization and intellectualization of automobiles, Sunrise Technology is an automobile chip company based on the local market and facing the international market. At the starting point of the chip manufacturing process, Sunrise Technology has developed the first 7nm smart cockpit chip "Dragon Eagle One" in China, which breaks the market situation that the advanced process products of automobile chips are monopolized by overseas manufacturers.

  

  7nm advanced technology has brought great changes to the entire cockpit and application system. First, advanced technology improves the chip's main frequency and computing speed. The improvement of GPU, CPU and NPU computing power can bring more OS and middleware related application experience. Different from the relationship between traditional car manufacturers and users, the intelligent cockpit system continuously deepens and strengthens the relationship with users through software upgrades and other functions after the smart car is delivered to users, while the complete operating system and high computing chip in the intelligent cockpit can effectively support the collection, collection and feedback of user behavior data in the cockpit, thus providing a basis for the improvement of user experience.

  

  The second is to continuously improve the level of intelligence. In the past, high-speed interfaces rarely appeared in automobile chips, but now the application of high bandwidth requires high-speed interfaces and parallel processing capabilities. Advanced technology can bring high computing power, multiple high-speed interfaces, and parallel processing capabilities to support more sensors and display terminals.

  

  The third is the demand for AI computing power. Not only the automatic driving, but also the video, voice and graphics processing, and even the human-computer interaction between the vehicle and the driver are constantly enhanced and improved.

  

  Fourth, the chip iteration is accelerated. At present, the cycle of car model change has been shortened from 5 to 8 years to 1 to 2 years, and new functions are emerging constantly; The upgrade cycle of corresponding on-board chips has been shortened from 5 to 8 years to 2 to 3 years.

  

  Through a "Dragon Eagle 1" SoC chip, it can realize auxiliary driving, AR-HUD, streaming media rearview mirror, vehicle HD 4K multi-screen and digital instrument panel. In response to the demand of vehicle-mounted games, we should first meet the operation status of the mobile phone and the mobile phone without difference, including the resolution, refresh rate and other indicators. Our engineers have also done a lot of adaptation work to support the smooth operation of 3D games such as King Glory and Ultimate Flying Car on "Dragon Eagle One".

  

  There are many new demands and application points in China's smart car market. Core Engine Technology will work with the upstream and downstream industries of the entire smart car industry to continuously launch chip products that meet the new demands and applications, to actively participate in and help the process of China's smart car.
