Seamless, Real-Time Embedded Processors

Arm Cortex-R real-time processors offer high-performance computing solutions for embedded systems where reliability, high availability, fault tolerance, and real-time responses are needed. Cortex-R5 builds on the feature set of Cortex-R4 with enhanced error management, extended functional safety, and SoC integration features that suit it for use in deeply embedded real-time and safety-critical automotive, industrial, and mass storage systems.

Features and Benefits

Functional Safety Support

Advanced safety features, including a flexible second core for redundancy or performance, improved bus protection, and error correction code, together with a safety package, mean Cortex-R5 is ideally suited for the development of safety-critical products.

Efficient High-Performance Processing 

Dual core configuration enables twice the performance of previous Cortex-R processors within a single cluster. The CPU is capable of dual issuing of instructions and has an option vector floating point instruction extension, delivering efficient, high-performance computing.

System-Level Integration

Simplified integration of the processor with a dedicated peripheral port and an accelerator coherency port enables integration into multi-master systems, allowing data sharing with accelerators.
