ARM processor Cortex-A65AE

dual corefor automotive applications

The First Multithreaded DynamIQ CPU with Split-Lock The Arm Cortex-A family of high-throughput efficiency processors is designed for memory intensive and demanding safety-critical tasks. The Cortex-A65AE is the first multithreaded Cortex-A CPU for automotive applications and safety critical tasks such as Advanced Driver-Assistance Systems (ADAS) and Gateway. It is designed for devices undertaking high throughput and safety critical tasks. The Cortex-A65AE is built on DynamIQ technology and benefits from its resilience and flexible multicore features. It has also been designed with Dual Core Lock-Step (DCLS), an advanced feature for increased fault-tolerance designs. Features and Benefits Simultaneous Multithreading The multithreaded processor, a first in the Cortex family, has an out-of-order execution pipeline and can execute two-threads in parallel on each cycle. Each thread can be at different exception levels and run different operating systems. Flexibility with Split-Lock Switch between split mode for performance for highest multicore performance or lock mode for safety for advanced multicore fault-tolerance with ASIL D hardware metrics. Provide additional flexibility for future mixed-criticality applications. Throughput Efficiency The Cortex-A65AE features an advanced microarchitecture designed for performance density and delivers high-throughput efficiency for memory intensive workloads in constrained thermal budgets.
