Part four wraps this blog series up with a discussion around virualization and 安全 for in-vehicle infotainment (IVI).
For the cockpit domain controller, virtualization is split between safety critical and noncritical functions, as depicted in the figure below. The safety critical 应用程序 are separately threaded to the hardware layer and are typically ISO26262 compliant to ASIL-B.

The safety critical nature of the application, along with connectivity exposure in the platform, creates the need for 安全 measures in the system design. 这些包括:
- 安全启动
- 入侵检测
- Secure over-the-air update strategies
- Enhanced Protection from cyber attacks
- Device tampering detection
- Embedded 安全 management
It is well known that hypervisors create performance inefficiencies. 微米 is working with key partners to implement direct memory virtualization where the hypervisor is replaced by a memory platform containing Single Root I/O Virtualization (SRIOV), which works directly in hardware, striving towards eliminating the need for a software-based hypervisor.
The Cockpit of the Future
With the continued migration of the automotive industry away from single vehicle ownership to fleet/shared ownership, 随意组合, and ultimately autonomous vehicles, the automotive interior will drastically change. Every seat in the vehicle interior has equal value moving forward. The consumers of the future will expect a seamless and consistent experience as they move from vehicle to vehicle within a fleet.
With respect to the architecture, it is 清晰的 the application of the domain space will be distributed amongst all the seating positions. There is no single architectural direction emerging at this point; however, several key points are becoming 清晰的:
- The amount of required computing will very likely be distributed in the system.
- AI will play a very important role in a successful user experience, vastly increasing computing needs
- Power consumption of the domain system will become more critical
微米’s advanced re搜索 in the areas of memory virtualization,, along with fundamental re搜索 in optimizing the power and calculation efficiency of AI, are playing an important role in charting the direction of the future automotive consumer experience.
After an amazing 88 years of evolution, the automotive industry continues to advance the user experience to new levels at a blinding pace. 作为数据可扩展性, 安全, and application developments in the areas of AI, 物联网, 移动性向前发展, 微米 continues to play a key role in optimizing the enablement of consumer expectations as well as the cost-effective deployment of next-generation transportation worldwide. The automotive market represents the next major growth area for the memory business, and 微米 is deeply involved in working closely with our automotive partners and customers to assure continued leadership in this market.
