Cortex-R Series

Ultimate Reliability for Embedded Real-Time Processing

The ARM Cortex-R real-time processors offer high-performance computing solutions for embedded systems where reliability, high availability, fault tolerance, maintainability and deterministic real-time responses are essential.

The Cortex-R series processors provide fast time-to-market through proven technology shipped in billions of products, and leverages the vast ARM ecosystem and global, local language, 24/7 support services to ensure rapid and low-risk development.

Cortex-R series processors deliver fast and deterministic processing and high performance, while meeting challenging real-time constraints in a range of situations. They combine these features in a performance, power and area optimized package, making them the trusted choice in reliable systems demanding high error-resistance.

Cortex-R Series Characteristics

 

Fundamental to the Cortex-R4Cortex-R5 and Cortex-R7 processors are key features that are demanded by deeply embedded and real-time markets such as automotive safety or wireless baseband, where high-performance, real-time, safe and cost-effective processing is required.

 

High performance: Rapid execution of complex code and DSP functionality

  • High performance, high clock-frequency, deeply pipelined micro-architecture
  • Dual-core multi-processing (AMP/SMP) configurations
  • Hardware SIMD instructions for very high performance DSP and media functions  

Real-time: Deterministic operation to ensure responsiveness and high throughput

  • Fast, bounded and deterministic interrupt response
  • Tightly Coupled Memories (TCM) local to the processor for fast-responding code/data
  • Low-Latency Interrupt Mode (LLIM) to accelerate interrupt entry

Reliable: Detects errors and maintains system operation

  • User and privileged software operating modes with Memory Protection Unit (MPU)
  • ECC and parity error detection/correction for Level-1 memory system and buses
  • Dual-Core Lock-Step (DCLS) redundant core configurations

Cost effective: Fast time-to-market and customizable features

  • Best-in-class energy and die area/cost efficiency
  • Configuration to include/exclude features to optimize power, performance and area
  • Fast development and testing with configurable debug breakpoints and watchpoints through CoreSight™ debug access port with embedded trace module options
