ARM processor Cortex-A78AE

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 heterogenous 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. 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.
