Highest Performance CPU with Split-Lock
Cortex-A78AE is the highest performance Cortex-A processor designed for devices undertaking complex and demanding safety-critical tasks. The Split-Lock capability with second-generation Dual Core Lock-Step (DCLS) enables flexible operations at the highest levels of safety. With the ability to run different workloads concurrently and a 30 percent performance uplift compared to its predecessor, Cortex-A78AE offers the scalable, efficient, heterogeneous compute required for automated driving and autonomous industrial systems.
Features and Benefits
The Cortex-A78AE features an advanced energy-efficient microarchitecture designed for performance density to deliver highest peak and sustained single-thread performance in thermally constrained fanless designs.
Options for multicore, multi-cluster, accelerator ports and heterogenous compute configurations offer the ability to run different workloads or application footprints, allowing the deployment of the same SoC compute architecture into different domain controllers.
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.
We have added a new capability to Arm Split-Lock technology called hybrid mode. 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.
Where Innovation and Ideas Come to Life
Any faults and failures may be life threatening so automotive systems demand higher levels of functional safety. 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.
