ARM and Panasonic: Accelerating AI-Driven SDVs

Arm Holdings plc (ARM) and Panasonic Automotive Systems Co., Ltd. (PAS) have recently announced a strategic partnership aimed at standardizing automotive architecture for Software-Defined Vehicles (SDVs). This collaboration, driven by their active participation in the SOAFEE initiative, seeks to promote greater collaboration and standardized software development across the automotive market. The partnership will focus on several key initiatives to advance AI-driven SDVs and accelerate industry development cycles.

Firstly, the partnership will leverage the device virtualization framework VirtIO to decouple automotive software development from hardware, enabling more flexible and efficient development cycles. By standardizing interfaces between software stacks and underlying hypervisors and chipsets, automotive partners can easily adopt the latest technology generations optimized for their needs. This results in accelerated innovation, reduced costs, and improved time-to-market for automotive partners.

Secondly, the partnership will utilize VirtIO-based Unified HMI to standardize zonal architecture, distributing GPU loads from the central ECU to multiple zonal ECUs. This architecture reduces heat generation and harness weight, enhancing overall vehicle efficiency. The flexible partitioning in the Mali™-G78AE GPU of zonal ECUs allocates dedicated hardware resources to different workloads, enabling deterministic graphics performance. This not only optimizes resource utilization but also allows for better isolation and security between different vehicle systems, improving the overall performance and reliability of SDVs.



Thirdly, the partnership aims to ensure environmental parity from cloud to car by maintaining the same Arm CPU architecture and VirtIO device virtualization framework in both cloud virtual hardware and automotive hardware. This initiative enables software developers to begin their work before physical silicon is available, accelerating automotive development cycles. Additionally, it allows for the bridging of the gap between virtual and physical automotive systems, further enhancing the potential of AI-driven SDVs.

Lastly, the partnership will expand VirtIO standardization to encompass more automotive applications, including standardizing interfaces for Real-Time Operating Systems (RTOS) to decouple Advanced Driver Assistance Systems (ADAS) software from hardware dependencies. This will enable faster innovation and easier integration of new technologies, driving the adoption of SDVs and aligning with the growing global SDV market, expected to reach $210.88 billion by 2032, growing at a CAGR of 19.4% (Precedence Research).

In conclusion, the partnership between Arm and Panasonic Automotive is a significant step towards advancing AI-driven Software-Defined Vehicles. By adopting and extending the device virtualization framework VirtIO, they aim to decouple automotive software development from hardware, accelerating industry development cycles. This collaboration involves several key initiatives that will enable automakers and tier-1 suppliers to adopt the latest generations of technology optimized for their needs and use cases, ultimately driving the growth and adoption of AI-driven SDVs.
