Zena CSS 基于 Armv9 AE（IT之家注：汽车增强）技术组合构建，是 Arm 第一个用于 AI 定义汽车 (AIDV) 的预集成和预验证平台，包含至多 16 个 Cortex-A720AE CPU、基于 Cortex-R82AE 的安全岛、CMN S3AE 互连总线、运行时安全引擎，可选 Mali-C720AE ISP、Mali GPU 和自定义IP。
传统汽车开发流程需要为每种车型和每个应用程序开发定制硬件和软件堆栈，代价共昂，而 Zena CSS 使得OEM 和芯片提供商能够重用架构和软件，加速全球车辆交付，简化系统开发和集成，同时简化功能安全和信息安全认证。
Arm 表示，未来数年大多数 OEM 将基于 Zena CSS 系列产品进行构建。
