Zonal Architecture for Centralized Compute

Each vehicle on the road contains around a hundred microcontrollers (MCUs) to operate lower-level functions, such as electric seats, transmission changes, and range reporting. As more digitalization takes place across the vehicle and computing complexity increases, these MCUs and ECUs cannot remain as independently operated components. A move toward a zonal and centralized compute architecture is essential.

Next Generation Vehicle Architecture Migration with Arm and NXP

Vehicles of the future will be radically different to those we drive today. Rising demands on electronics and higher compute requirements, combined with the growth of AI within vehicle architectures, are enabling a range of new driver functions and unit updates. Join Arm and NXP's upcoming webinar to learn about the challenges faced by motor manufacturers in enabling software-defined vehicles (SDVs), Arm’s high performance, power efficient portfolio with enhanced functional safety and security features. and the opportunities to accelerate the migration of vehicle portfolios through to new E/E architectures.
