Arm’s AI-Driven Zena CSS: Revolutionizing Vehicle Tech

Arm Unveils Zena Compute Subsystems for AI-Driven Vehicles

Arm has launched the Zena Compute Subsystems (CSS) platform this week, aiming to revolutionize automotive technology with robust AI integration. Targeted at car manufacturers and electronic suppliers, this platform addresses the rising demand for AI-driven solutions within vehicles.

The Zena platform arises amidst the shift from “software-defined vehicles” (SDV) to “artificial intelligence-defined vehicles” (ADV), facilitating faster development and seamless integration of AI-driven automotive subsystems. This evolution intends to embed AI not only in cloud-based systems but directly into vehicles themselves, enhancing everything from driver assistance features to infotainment systems.

Why Zena Matters

Dipti Vachani, Arm’s Senior Vice President for automotive, emphasized the platform’s potential to expedite AI application and market entry of new car models. Built on the Armv9 Automotive Enhanced architecture, Zena CSS caters to automotive needs while promoting innovation.

Key Features of Zena CSS

The first generation of Zena CSS integrates a 16-core Cortex-A720AE processor cluster, a real-time Cortex-R82AE security block, and a dedicated security zone supported by Arm TrustZone. The CMN S3AE interface ensures efficient data exchange between systems. This setup undergoes pre-validation, allowing for swift implementation without compromising safety.

Boosting Efficiency

Vachani claims Zena CSS can decrease development time by up to 12 months and reduce engineering workforce needs by 20%. This modular platform allows easy integration of custom Arm-compatible solutions, including advanced graphics and AI accelerators, enhancing both performance and efficiency.

Zena CSS’s adaptability allows it to scale with various car models, quickly boosting block performance by adding hardware resources. The software, which is immediately deployable on simulated models, can cut development timelines by up to two years.

Open-Standard Foundation

Built on the SOAFEE open standard, Zena CSS is designed for embedded edge systems. While companies like Infineon and NXP focus on RISC-V architecture, Arm offers a holistic approach, promoting client-created solutions within its ecosystem using the Zena CSS platform. Access to the platform has begun, with expanded availability planned, and software components are already open to developers.
