One-core multiple screens in smart cockpits have attracted more attention. A brief discussion on one-core multiple screens in smart cockpits

According to the latest data from AutoForecast Solutions (AFS), an automotive industry data forecasting company, as of October 30, due to chip shortages, the global auto market has reduced production of approximately 3.905 million vehicles this year. Although the overall chip shortage has been alleviated, local and individual chip shortages still exist, and structural core shortages still exist. Coupled with the impact of the epidemic and other factors, the production capacity of individual automobile manufacturers is still limited.

In addition, the popularity of automobile electrification and intelligence is accelerating, and many new car-making forces are advancing. The demand for automobile chips has not decreased. Smart cockpits, autonomous driving, and Internet of Vehicles have begun to be launched on a large scale, and one-core multiple screens have attracted more attention.

The acceleration of automobile intelligence has made smart cockpits more and more technologically advanced, with more and more cool functions being integrated into them. Moreover, the trend of "one core, multiple screens", multi-screen integration and multi-screen interaction is becoming more and more obvious. Various human-computer interactions such as gestures, voice, and touch are beginning to be widely used in automotive electronics. Many chip manufacturers have launched "one core, multiple screens" solutions.

Xinchi X9 series chips

Xinchi Intelligent Cockpit X9 series chips are car-grade automotive chips specially designed for the new generation of automotive electronic cockpits. They integrate high-performance CPU, GPU, AI accelerator, and video processor to meet the powerful requirements of new generation automotive electronic cockpit applications. Increasing demands for computing power, rich multimedia capabilities, and more. In addition, the X9 series chips also integrate PCIe3.0, USB3.0, Gigabit Ethernet, and CAN-FD, which can be seamlessly applied to vehicle-mounted systems at a lower cost. This chip also uses a safety island including Cotex-R5 dual-core lockstep mode, which can be used in scenarios with strict safety performance requirements.

Renesas H3 solution

Renesas H3 is a 16nm process automotive SoC based on A57/A53. It adopts ARM's 64-bit CPU core architecture and can achieve a processing performance of 40,000 DMIPS. Using GX6650 as the 3D graphics engine can provide drivers with timely and reliable information display. Based on the latest architecture provided by Imagination Technologies, H3’s shading calculation performance is approximately three times that of H2.
