Overview

The Arm Cortex-R5 processor forms a simple migration path from the Cortex-R4 processor, and onwards to the higher performance Cortex-R8 and Cortex-R52 processors. The Cortex-R5 processor builds on the feature set of the Cortex-R4 with enhanced error management, extended functional safety, and SoC integration features, for use in deeply embedded real-time and safety-critical systems.

Key features

  • Higher system performance and Advanced system level integration features - Dual-core configurations which enable twice the performance with Accelerator Coherency Port (ACP) and Micro Snoop Control Unit (micro SCU) maintaining data cache coherency with DMA I/O for both cores.
  • Improved reliability and safety features - Low-Latency Peripheral Port (LLPP), enhanced Memory Protection Unit (MPU) and enhanced ECC support.
  • Lock-step configurations - Second core provides redundancy for safety critical applications.
  • Extended functional safety support - Safety Documentation simplifies the certification effort for standards such as ISO26262 and IEC 61508, and enables higher levels of certifications.

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.
