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
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.
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.
The Cortex-A65AE features an advanced microarchitecture designed for performance density and delivers high-throughput efficiency for memory intensive workloads in constrained thermal budgets.
Where Innovation and Ideas Come to Life
Cortex-A65AE is designed for high-throughput applications, such as sensor fusion and vision-based ADAS systems. It delivers substantial gains in throughput efficiency and contributes toward the highest Automotive Safety Integrity (ASIL) standards required for fully autonomous vehicles.
