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.
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.
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.
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.
Controllers are widely used in industrial applications. Cortex-M4 comes equipped with essential microcontroller features, including low latency interrupt handling, integrated sleep modes, and debug and trace capabilities, making it the ideal processor for industrial control.

Software Test Libraries
Arm's Software Test Libraries provide diagnostic coverage to address functional safety requirements for ISO 26262 and IEC 61508 systems, with flexible execution scheduling minimizing the run-time impact on applications.
Designing a secure system-on-chip is challenging and time-consuming. To help designers get to market quickly, Arm provides the IP blocks needed to build a system. Corstone is a solution for architecting the system, making it secure and able to handle the complex power control infrastructure, while balancing trade-offs between performance and power.
AMBA System Controllers
The Arm AMBA specifications are the standard for on-chip communication. AMBA is an open standard for the connection and management of functional blocks in a system on chip (SoC). It facilitates “right the first time” development of multi-processor designs with large numbers of controllers and peripherals.
Bixi, a touch-free and portable controller, facilitates a new level of
interaction with smart devices. Bixi communicates with other
smart devices, applications, and smart objects; it recognizes
intuitive hand movements, such as waves and half-waves,
and translates them into instructions.
Arm-based chips, device architectures, and technologies orchestrate the performance of everything that makes modern life possible — from smartphones to agricultural sensors and from medical instruments to servers.
