AM68 可扩展处理器系列采用不断发展的 Jacinto™ 7 架构，面向智能视觉摄像头和通用计算应用，基于 TI 在视觉处理器市场上十多年所积累的广泛先进市场知识而构建。AM68x 系列专为工厂自动化、楼宇自动化和其他市场中广泛的成本敏感型高性能计算应用而构建。

AM68 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技术，并且系统集成度高，可为高级视觉摄像头应用实现可扩展性和更低的成本。关键内核包括用于常规计算的新款 Arm 和 GPU 处理器、具有标量和矢量内核的下一代 DSP、专用深度学习和传统算法加速器、集成的下一代成像子系统 (ISP)、视频编解码器和隔离式 MCU 岛。所有这些都由工业级安全硬件加速器提供保护。

通用计算内核和集成概述：对 Arm® Cortex®-A72 的独立双核集群配置有助于实现多操作系统应用，而且对软件管理程序的需求非常低。最多两个 Arm® Cortex®-R5F 子系统能够管理低级的时序关键型处理任务，使 Arm® Cortex®-A72 内核不受应用的影响。TI 的第 7 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，支持更高的位深度，并且具有面向分析应用的特性。集成的诊断和安全功能可支持高达 SIL-2 级别的运行，同时集成的安全功能可保护数据免受现代攻击。CSI2.0 端口支持多传感器输入。

主要高性能内核概述：C7000™ DSP 下一代内核（“C7x”）将 TI 先进的 DSP 和 EVE 内核整合到性能更高的单个内核中，并增加了浮点矢量计算功能，可实现对旧代码的向后兼容性，同时简化软件编程。即使在 105°C 和 125°C 的最坏情况结温下运行，新型“MMA”深度学习加速器也可在业界超低的功率范围内实现高达 8 万亿次每秒运算 (TOPS) 的性能。专用的视觉硬件加速器可提供视觉预处理，而不会影响系统性能。C7x/MMA 内核仅可用于 AM68 级处理器中的深度学习功能。
