The Arm® Cortex®-M4 processor is a high performance embedded processor with DSP instructions developed to address digital signal control markets that demand an efficient, easy-to-use blend of control and signal processing capabilities. The processor is highly configurable enabling a wide range of implementations from those requiring floating point operations, memory protection and powerful trace technology to cost sensitive devices requiring minimal area.


  • Gain the advantages of a microcontroller with integrated DSP, SIMD, and MAC instructions that simplify overall system design, software development and debug
  • Accelerate single precision floating point math operations up to 10x over the equivalent integer software library with the optional floating point unit (FPU)
  • Develop solutions for a large variety of markets with a full-featured Arm v7-M instruction set that has been proven across a broad set of embedded applications
  • Achieve exceptional 32-bit performance with low dynamic power, delivering leading system energy efficiency due to integrated software controlled sleep modes, extensive clock gating and optional state retention.


The Cortex-M4 has been specifically developed for partners to design high-performance low-cost devices for a broad range of digital signal control embedded market segments.
