汽车SoC combines 500 eTOPS with high-res image and radar processing
The CV3 domain controller family represents a 42x increase over Ambarella’s prior automotive family. Featuring up to 16 Arm Cortex-A78AE CPU cores, the CV3 provides up to a 30x boost in CPU performance over the prior generation in support of autonomous vehicle (AV) software applications. According to Ambarella, this product family enables centralized, single-chip processing for multi-sensor perception, including high-resolution vision, radar and ultrasonic. In addition, it empowers deep fusion for multiple sensor modalities and AV path planning. The result is robust ADAS and L2+ to Level 4 autonomous driving (AD) systems with greater levels of environmental perception in challenging lighting, weather and driving conditions for both driver viewing and machine perception.
“借助我们的CV3 AI域控制器家族，我们现在有能力用单个芯片运行完整的ADA和广告堆栈，同时提供前所未有的性能和功率效率，” Ambarella首席执行官兼总裁Fermi Wang说。“通过增强我们的芯片ISP，以及可以利用我们的OCULII自适应AI算法的同时进行雷达处理，Ambarella正在帮助汽车行业解锁所有环境条件的更高感知准确性，以实现自治动力的承诺。透明
CV3标志着首次Ambarella next-generation CVflow architecture, which continues the company’s algorithm-first design philosophy. This drove the development of the on-chip neural vector processor (NVP), with up to 500 eTOPS of AI compute, high power efficiency and support for the latest advancements in neural network (NN) inferences. The NVP is also enhanced to run advanced radar perception software, such as the Oculii adaptive AI software algorithms. This is complemented by a new floating-point general vector processor (GVP) designed to offload classical computer vision and radar processing from the NVP engines, and floating-point-intensive algorithms from the Arm CPUs.
The CV3 family’s hardware scalability allows customets to unify their software stacks across their entire retail portfolios, while reducing the cost and complexity of software development, Ambarella promises. With this scalability, the company hopes to address the rising complexity of automotive software by providing an alternative to the fragmented ADAS SoC offerings from competitors. Additionally, the CV3 family accelerates automakers’ development timelines while simplifying the deployment of new features by providing the headroom for a single, robust over-the-air (OTA) update implementation.
The product family has multiple options to meet the strategies of OEMs and Tier 1s, alike, from its low-power SoCs for regulatory-class, forward-facing cameras, scaling up to premium SoCs for Level 4 fully automated driving. Likewise, It supports both central and zonal architectures. In addition to covering the whole AD stack, the CV3 can simultaneously process in-cabin sensing applications, including driver and occupant monitoring.
CV3还集成了Ambarella的下一代ISP，有助于将图像信号处理质量提高到新的水平。通过同时支持多达12个物理或20个虚拟摄像头，单个CV3可以处理整个传感器套件，对于典型的L2+部署，该套件包括10个摄像机，5个雷达模块和众多超声传感器。此外，高性能立体声和密集的光流动发动机提供了更大的深度和运动感知。
Additional features of the new CV3 central domain controller family include:
- 适用于3D环绕视图渲染等应用的汽车GPU
- 硬件安全模块，启用不同域的隔离和安全软件提供
- PCIE高速界面的高速界面
- 在影子模式下处理OTA软件更新和测试软件堆栈的处理净空
预计CV3家族中的第一批SOC将在2022年上半年进行采样。
