Smallest Real-Time Processor

The Cortex-R family of processors is designed for applications where high-performance, real-time, safe, and cost-effective processing is required. Cortex-R4 offers excellent energy efficiency, cost effectiveness, and fault tolerance for embedded applications including automobiles, cameras, and disk drive controllers.

Features and Benefits
Real-Time Deterministic Microarchitecture

Constructed using a flexible memory system with scalable, fast tightly coupled memory, this processor meets the high-performance needs of real-time embedded systems where deterministic execution is critical enabling real-time deadlines to be met.

High-Performance Efficient Processing 

A dual-issue, high-performance pipeline, with capability for hardware divide and single and double precision floating point extensions, supports the smallest and lowest-power Cortex-R processor, enabling efficient performance.

Built-In Error Handling

Prioritize reliability and error management through the inclusion of an optional redundant core for cycle-by-cycle checking, combined with the integrated memory protection unit and built-in error correcting code.

Use Cases
Where Innovation and Ideas Come to Life

Internet of Things (IoT) is bringing connected devices together into a global network of distributed intelligence. As mobile, cloud, and big data make IoT a reality, the size and low power consumption of Cortex-R4 make it ideal for use in new, affordable IoT platforms that enable smart home, consumer, and business uses.
