ARM processor Cortex-A520AE

High-Efficiency Arm Cortex-A CPU for Safety-Critical Applications Arm Cortex-A520AE is a high-efficiency Armv9.2 CPU designed to support the demanding safety-critical tasks of the next generation of SDVs. The merged-core micro-architecture and DynamIQ technology deliver new levels of scalability to address the needs of zonal, in-vehicle infotainment and advanced driver-assistance (ADAS) systems. It’s compatible with Arm Cortex-A720AE for heterogenous compute, where the perfect balance of efficiency and performance can be achieved. Features and Benefits Flexibility with Split-Lock Designed to balance performance and safety across quality management (QM), ISO 26262 ASIL B and ASIL D use cases. Boot in lock mode for safety-critical applications, or boost performance in split or hybrid mode, utilizing the configurable safety features, such as transient fault protection (TFP) and software test libraries (STL), for increased fault detection. Efficiency First Design Micro-architecture improvements and the merged-core micro-architecture ensure power efficiency in the smallest silicon footprint to support the low power demands of EVs. Cortex-A520AE delivers these efficiencies, while bringing a significant performance uplift over previous generations to suit the emerging workloads of the SDV. Advanced Features Based on the Armv9.2-A architecture, it delivers new features designed to increase performance for AI and ML workloads, enhance security for the SDV, and ensure quality of service that is critical to automotive applications. Architecturally compatible, Cortex-A520AE can be paired with the Cortex-A720AE CPU within a single DSU-120AE cluster.
