Overview

The Cortex-A7 processor provides up to 20% more single thread performance than the Cortex-A5 and incorporates all features of the high-performance Cortex-A15 and Cortex-A17 processors, including virtualization support in hardware, Large Physical Address Extensions (LPAE), NEON, and 128-bit AMBA 4 AXI bus interface.

Key features

  • In-order 8 stage pipeline - Improved dual issue, branch prediction and memory system performance. It features 64-bit load-store path, 128-bit AMBA 4 AXI buses and increased TLB size (256 entry).
  • Integrated, Configurable Size Level 2 Cache Controller - Provides low-latency and high-bandwidth access to up to 1MB of cached memory in high-frequency designs, or designs needing to reduce the power consumption associated with off-chip memory access. The L2 cache is optional on Cortex-A7.
  • Support Armv7-A extensions - Hardware Virtualization and Large Physical Address Extensions (LPAE) enables the processor to access up to 1TB of memory.
  • big.LITTLE technology - First LITTLE processor architecturally compatible with compatible with Cortex-A15 and Cortex-A17 for various big.LITTLE processor combinations.

Announcing Arm AGI CPU: The silicon foundation for the agentic AI cloud era

For the first time in our more than 35-year history, Arm is delivering its own silicon products – extending the Arm Neoverse platform beyond IP and Arm Compute Subsystems (CSS) to give customers greater choice in how they deploy Arm compute – from building custom silicon to integrating platform-level solutions or deploying Arm-designed processors.

Top 5 Reasons why CPU is the Best Processor for AI Inference

Advanced artificial intelligence (AI), like generative AI, is enhancing all our smart devices. However, a common misconception is that these AI workloads can only be processed in the cloud and data center. In fact, the majority of AI inference workloads, which are cheaper and faster to run than training, can be processed at the edge – on the actual devices.
