描述 Description

AM62Ax 是 Sitara™ 汽车级异构 Arm® 处理器系列的扩展，具有嵌入式深度学习(DL)、视频和视觉处理加速、显示接口及广泛的汽车外设和网络选项。AM62Ax 专为一系列成本敏感型汽车应用（包括驾驶员和车内监控系统与下一代电子后视镜系统）以及工厂自动化、楼宇自动化、机器人和其他市场中的广泛工业应用而构建。AM62Ax 对成本进行了优化，能够以业界卓越的功耗/性能比为传统和深度学习算法提供高性能计算，并具有很高的系统集成度，从而使支持独立电子控制单元 (ECU) 中多种传感器模式的高级汽车平台实现可扩展性和更低的成本。

AM62Ax 包含多达四个具有 64 位架构的 Arm® Cortex®-A53 内核、一个具有图像信号处理器 (ISP) 和多个视觉辅助加速器的视觉处理加速器 (VPAC)、多个深度学习 (DL) 和视频加速器、一个 Cortex®-R5F MCU 通道内核以及一个 Cortex®-R5F 器件管理内核。Cortex-A53 提供了 Linux 应用所需的强大计算元件，以及驾驶员监控等基于视觉计算的传统算法的实现。TI 的第七代 ISP 以现有出色的 ISP 为基础，能够灵活地处理更广泛的传感器套件（包括 RGB-IR），支持更高的位深度，并且具有面向分析应用的特性。关键内核包括德州仪器 (TI) 具有标量和矢量内核的下一代 C7000™ DSP (C7x)，以及专用 MMA 深度学习加速器，该加速器在典型的汽车最坏情况结温 125°C 下运行时，可在业界超低的功耗范围内实现高达 2TOPS 的性能。

3 端口千兆位以太网交换机具有一个内部端口和两个支持 TSN 的外部端口，可用于启用工业网络选项。此外，AM62Ax 中随附广泛的外设集，可实现 USB、MMC/SD、摄像头接口、OSPI、CAN-FD 和 GPMC 等系统级连接，用于将主机接口并行连接到外部 ASIC/FPGA。AM62Ax 通过内置 HSM（硬件安全模块）支持安全启动来实现 IP 保护，还为便携式和功耗敏感型应用提供高级电源管理支持。
