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

Industrial technology continues to lead the way in the use of connected devices and the internet of things (IoT). The size, reliability, and low power consumption of Cortex-R4 make it ideal for use in efficient, continuous industrial IoT (IIoT) operations.
