Cortex-R8 Processor

The ARM® Cortex®-R8 processor has the highest performance of any real-time processor, delivering advanced real-time processing for a wide range of demanding, deeply embedded applications. The Cortex-R8 processor is the latest member of the Cortex-R family, offering a wide set of features for advanced applications that require the highest levels of real-time performance. It builds on the highly successful Cortex-R7 processor, featuring an advanced 11-stage, superscalar, out-of-order pipeline, for fast performance at high clock frequencies. It also incorporates an integrated Generic Interrupt Controller (GIC), Snoop Control Unit (SCU) and timers to further reduce latency and enable fully coherent multiprocessing.

Key Benefits

  • The highest performance real-time processor – double the total performance of Cortex-R7
  • Always reacts to system events in a fast and deterministic manner
  • Coherency between up to four cores, simplifying software development
  • Tightly Coupled Memory to keep critical instructions and data close to the core for fast, immediate and deterministic processing
  • Immediate, deterministic and coherent control of system peripherals


The Cortex-R8 processor is designed for implementation on advanced silicon processes with an emphasis on energy efficiency, real-time responsiveness, advanced features and ease of system design. Key application areas include:
