NXP integrates Ethernet IP from Imagination
As Ethernet connectivity is increasingly is increasingly setting foot in automotive engineering, it finds its way into automotive chips. The latest proof of this trend is the license agreement between Imagination Technologies and NXP: The latter will integrate Imaginations Ethernet Packet Processor (EPP) into its S32 vehicle communications processors.

The NXP processors address the challenges of routing and processing the rapidly growing high-speed data in vehicle networks. Imagination’s EPP IP accelerates the routing of Ethernet packets while processor cores focus on providing valuable new vehicle services with cloud connectivity. The S32 network processors combine ISO 26262 Automotive Safety Integrity Level (ASIL) D functional safety, advanced hardware security, high-performance real-time and application processing, and vehicle network acceleration for service-oriented gateways, domain controllers and safety co-processors.

For Brian Carlson, Global Marketing Director for Vehicle Control and Networking Solutions at NXP, the collaboration with Imagination leveraging NXP automotive and networking expertise resulted in the EPP IP offering flexibility and programmability to address demanding, new vehicle Ethernet networking requirements driven by the automotive industry transformation to electrified and autonomous connected vehicles.

Imagination’s multi-gigabit EPP IP provides a flexible core that supports smart routers and multiple switches, or a combined switch and router configuration. It uses a hardware and software framework, combined with hardware accelerators and a high-speed flexible DMA fabric, to provide a complete and highly-optimised solution that can scale up to 16 ports and 12 million packets per second. It utilises advanced design techniques complemented by a rich set of features to deliver optimum power/performance while maintaining consistent connectivity.

According to James Hodgson, Principle Analyst, ABI Research, the next-generation of ADAS and automated driving functions will require a step-change in vehicle computing architecture, including high-bandwidth and low-latency networking. Since Imagination’s EPP IP features multiple gigabit Ethernet ports it enables automakers to begin early developing new vehicle architectures that are futureproofed for throughput and latency requirements. By designing its EPP IP with functional safety requirements in mind, Imagination can support automakers in leveraging gigabit Ethernet for mission-critical applications.”
