Cortex-R 系列

Fast response - optimized for high performance, hard real-time applications

The ARM® Cortex®-R real-time processors offer high-performance computing solutions for embedded systems where reliability, high availability, fault tolerance and/or deterministic real-time responses are needed. Cortex-R processors are used in products where performance requirements and timing deadlines must always be met. In addition, Cortex-R processors are used in electronic systems which must continue functioning in the presence of faults so that damaging situations cannot occur, for example, a head crash in a magnetic disk drive.

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.

Cortex-R characteristics

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
