Renesas targets high-volume markets with new generation of its R-Car SoCs
在接下来的几年中，在2级以上和3级的自动驾驶将到达车辆类，不仅是技术，而且是经济的，而且在大批量领域。在那里，价格压力比高级品牌更为明显。日本芯片制造商Renesas现在正与最新一代的车辆处理器陷入困境。
R-car V4H生成的SOC旨在处理众多环境传感器信号，并取决于设备和设计，使车辆能够自动驾驶，超越，更换车道并执行类似的操作。但是，如果电子设备不再能够找到自己的出路，则驾驶员必须随时立即进行干预。此外，车辆可以在一定范围内停车。尽管如此，Renesas Chip仍然具有足够的硬件储备，可以唤起仪表板的视觉效果。
Renesas has placed special emphasis on the fact that the corresponding control computers in the car do not require active cooling: These computers are usually installedinside the habitacle of the vehicle,汽车设计师不喜欢嘈杂的粉丝来冷却电子产品。
V4H SOC的性能以及经济处理是通过复杂的半导体技术和建筑技巧的结合来实现的。例如，Renesas使用7NM技术进行芯片，以及用于特定任务的硬件加速器的选择。这使该设备能够达到每秒34个TERA操作的深度学习性能（顶部）。除了SAE 3级所需的激光雷达和雷达传感器外，该芯片还为360°环形视图提供了多达16台相机。
根据ISO 26262对功能安全, the SoC development process targets ASIL D systematic capability for all safety relevant IP. The signal processing portion of the R-Car V4H is expected to achieve ASIL B and D metrics for the real time domain.
除其他外，SOC包含四个ARM Cortex-A76核心，总性能为49kDmips，三个锁紧臂皮层R52核心，用于安全 - 关键任务处理器单元（GPU）。诸如CAN，以太网AVB，TSN和FlexRay等汽车典型接口以及两个4G PCIE接口可以与外界进行数据通信。

Renesas also provides a dedicated power solution for R-Car V4H based around the RAA271041 pre-regulator and the RAA271005 PMIC. This enables a highly reliable power supply for the R-Car V4H and peripheral memories from the 12V supply of the vehicle battery. These features enable low power operation while targeting ASIL D compliance for systematic and random hardware faults at very low BOM cost. This helps to minimize the effort of hardware and software development while reducing design complexity, cost, and time to market.
An R-Car V4H software development kit (SDK) is also available to perform faster and easier initial device evaluation, and software development including deep learning. The SDK offers full functionality for machine learning development, and optimization of embedded systems for performance, power efficiency, and functional safety. Complete simulation models are available, and the Renesas operating system agnostic software platform enables easier development of the software-defined car.
如果从头开始开发，Fixstars的Genesis平台使工程师能够通过其云解决方案从任何地方评估R车，并可以提供快速简便的CNN基准结果。
R-CAR V4H SOC的样本现已上市，批量生产定于2024年第二季度。
