Fast response - optimized for high performance, hard real-time applications
ARM offers Cortex-R4 and Cortex-R5 for use when efficiency in die area and power is most important, and Cortex-R7 and Cortex-R8 for the highest performing applications.
The Cortex-R series processors provide fast time-to-market through proven technology shipped in billions of products, supported by the vast ARM ecosystem. Cortex-R processors have been successfully adopted in many markets including:
Cortex-R processors are designed for implementation on advanced silicon processes for applications 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
- Multi-processing (AMP/SMP) configurations
- Hardware SIMD instructions for very high performance DSP and media functions
Real-time - deterministic operation to ensure responsiveness
- 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
