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
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.
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.
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.
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.
