High-Performance Armv8 Cortex-A CPU for Safety-Critical Systems

Cortex-A78AE is a high-performance Armv8A Cortex-A processor designed to meet the complex and demanding safety needs of the software-defined vehicle (SDV). Already silicon proven in the automotive market, it enables advanced ADAS functionality and new in-vehicle infotainment experiences for vehicle users. With ISO 26262 ASIL D Hardware Diagnostic and Systematic certifications, Cortex-A78AE can be used in conjunction with Arm Cortex-A65AE and DSU-AE to meet all application-class processor needs in vehicles.

Features and Benefits

Sustained Performance

The Cortex-A78AE features an advanced energy-efficient micro-architecture designed for performance density to deliver high peak and sustained single-thread performance in thermally constrained fan-less designs.
Scalable, Heterogeneous Compute

Options for multicore, multicluster, accelerator ports and heterogeneous compute configurations offer the ability to run different workloads or application footprints so the same SoC compute architecture can be deployed into different domain controllers.
Flexibility with Split-Lock

Switch between split mode for highest cluster-level performance, lock mode for advanced multicore fault-tolerance with ASIL D/SIL 3 hardware metrics, or hybrid mode to deliver higher compute availability to help achieve ASIL B/SIL 2 safety requirements.

Split-Lock Technology

 

Cortex-A78AE introduces the hybrid mode capability to Arm Split-Lock technology. Hybrid mode enables the cores to run independently or split, with only the Arm DynamIQ Shared Unit (DSU) running in lock mode. This enables our partners to achieve higher coverage and reduce testing downtime when targeting ASIL B/SIL 2 use cases.

Use Cases

Where Innovation and Ideas Come to Life

Autonomous Vehicles

Automotive systems demand higher levels of functional safety as any faults or failures may be life threatening. Cortex-A78AE provides a flexible, scalable, heterogeneous compute solution to meet the highest Automotive Safety Integrity Level (ASIL) standards required for advanced driver-assistance systems (ADAS) and autonomous driving.
