Analysis of the evolution trend of in-vehicle infotainment system chip

With the increasing demand for high-tech technology in the car, the most intuitive information entertainment system (IVI) has become more and more popular, graphical interface, rich multimedia functions, and the in-vehicle infotainment system. The market is growing rapidly. For the majority of chip manufacturers, how to better provide higher performance processors for the market becomes more and more important.

EEWORLD interviewed market research and consulting firm Strategy Analytics, automotive multimedia and communication services director automotive multimedia Richard Robinson, automotive multimedia communication service assistant director Roger C. Lanctot, automotive multimedia communication service analyst Li Jianyu and other experts on the hot topics and trends in the market Answered.

Q: At present, how is the differentiation of in-vehicle infotainment systems reflected?

Strategy Analytics: As cars become more versatile and “commoditized” (such as Bluetooth, USB, WiFi and 3.5mm audio interfaces), the car-to-vehicle differentiation becomes smaller and smaller.

Among them, some system-level differentiation features are as follows:

Larger size, higher resolution, multiple display unit architecture, which requires more processing power (including graphics processing capabilities);

The use of the HUD (head-up display) function is gradually increasing;

The embedded link capability introduces external applications directly into the in-vehicle system without the need for hotspot connections via smartphones or communication devices.

Q: What is the future development trend of in-vehicle infotainment systems?

Strategy Analytics:

Key development trends include:

Hybrid navigation: based on the conversion of the car's own map to the cloud map based on the background server, it can bring more updated map data and services;

Context awareness: integration of mobile terminal and sensor awareness;

Identity management: identification of the current vehicle driver identity in order to change the environment settings / entertainment content in the car - based on the car's own strategy or background strategy;

Global solutions: navigation, app application deployment, flexible interface

Remote vehicle data access and remote control, including:

User portal and mobile app

Data sharing with users, dealers, etc.

Strategy Analytics anticipates that the integration of single-processor multi-core virtualization, security and entertainment features in the vehicle based on ECU and control functions will gradually be recognized by automakers for a relatively long period of time in the future. And, features such as remote firmware update (FOTA) and remote car diagnostics will gradually replace the current variety of apps and entertainment applications.

Q: What is the current market size of the in-vehicle infotainment system SoC? What is the evolution trend?

Strategy Analytics: Overall, the market for in-vehicle infotainment SoCs will grow from $5.8 billion in 2013 to $7.2 billion in 2021. The evolution is as follows:

The application-oriented semiconductor market will grow from approximately $3.6 billion in 2013 to more than $5 billion in 2021 (ASIC/ASSP/PLD);

Pre-installed application processors (including SoCs for audio, media, navigation and telematics applications) will grow from $830 million in 2013 to $1.4 billion in 2021;

Larger in-car displays will require more powerful application processors, which will undoubtedly bring more opportunities to new entrants to the in-vehicle market such as nVidia;

Automakers are using more powerful application processors (multicore) to create virtualized architectures;

Multi-core processors will handle multiple capabilities such as navigation, media, communications, graphics, etc.;

Q: What are the current mainstream chip suppliers for in-vehicle infotainment systems? What are the characteristics of each family?

Strategy Analytics: Below is the top five IVI chip makers

Automakers are currently struggling with the choice of Intel, nVidia or Qualcomm's monolithic, powerful system-on-chip (SoC) to replace TI and Freescale's low-cost chips. The main obstacle to the current replacement of traditional low-cost silicon solutions with a single-chip system-on-chip is the industry's acceptance of a single processor and virtualization technology that handles both critical security functions and entertainment functions.

Renesas is the number one application processor supplier, mainly due to extensive business cooperation among the remaining Japanese car entertainment tier-1 suppliers (Japanese car entertainment tier 1 suppliers account for nearly 50% of the market profit in the industry) However, the performance of Japanese suppliers is declining).

Freescale is second, mainly due to its current cooperation with Ford (SYNC System). Freescale's goal is primarily to optimize multi-function application chips such as the i.MX series.

nVidia is in third place, but he is a new entrant to the automotive industry. In the past two years, the company's application processor has doubled its profits, and Strategy Analytics believes that this trend will continue this year.

Q: How do you see the evolution of the processor architecture of in-vehicle infotainment systems?

Strategy Analytics:

The mainstream core technology is that the system-on-a-chip (SoC) of 95% of IVI systems uses the ARM architecture.

The need to support multiple applications in fault tolerant systems is the main driver of multicore solutions;

System-level virtualization is another market driver in the multi-core market;

The market size of the Car System-on-Chip (SoC) cannot be compared to the market size of smartphones. Therefore, for SoC suppliers in the automotive field, the main area of ​​competition is to provide sufficient processing power. Tier 1 suppliers are very cost sensitive and they will choose the best cost-effective SoC to ultimately reduce the overall in-vehicle system manufacturing costs.
