Control and Performance for Mixed-Signal Devices 

The Cortex-M processor series is designed to enable developers to create cost-sensitive and power-constrained solutions for a broad range of devices. Cortex-M4 is a high-performance embedded processor developed to address digital signal control markets that demand an efficient, easy-to-use blend of control and signal processing capabilities.

Features and Benefits

Achieve More with Floating Point Processing

Reduce power consumption and extend battery life with 10x acceleration of single precision floating-point operations with the built-in floating-point unit (FPU). Combined with the Arm CMSIS-NN machine learning libraries, Cortex-M4 brings advanced intelligence to battery-powered embedded and IoT devices. 

Add DSP Functionality

Reduce chip system cost with combined control and signal processing in the same processor. Integrated Digital Signal Processing (DSP), SIMD, and MAC instructions simplify overall system design, software development and debug. Programmable in C and supported by a rich library of DSP functions, simplifies signal processing, reduces development effort, and brings DSP to the masses.

Get to Market Faster, Reduce Design Risk

Reduce risk and achieve first-time success by using one of the most widely deployed Cortex-M processors. With its broad ecosystem of software, tools, codecs, and other DSP code, it is easy to build on existing software to create advanced embedded products with less effort and a faster time to market.
