Trusted Arm Processors with Digital Signal Processing

As homes become smarter and appliance interfaces become more human-like, devices must be able to bridge the analog and digital worlds. This is driving more on-device processing than ever before, with advanced sensing, compute, and scalability across many applications—from voice to audio to sensor hubs to machine learning (ML).

Whether multi-sensor devices need dedicated digital signal processing (DSP) hardware or not, Arm and partners offer a step-change increase in on-device processing capability. This allows companies to innovate broadly and scale their product while meeting a wide range of requirements and applications.

The DSP extensions in Arm CPUs make DSP functionality accessible regardless of expertise. With efficient control code and high-performance DSP in a single processor, designers can reduce cost, area, and complexity, without compromising performance.

Features and Benefits

Increase Efficiency

Arm DSP extensions provide significant cost savings and resource requirements by replacing two processors with one. Signal processing is built into the processor so there is no need to add a dedicated DSP and learn a new unique DSP programming language. 

Reduce Complexity

DSP extensions reduce system-level complexity by removing the need for shared DSP communication, complex multiprocessor bus architectures, and other custom ‘glue’ logic between the processor and DSP. 

Reduce BOM Costs

By using DSP extensions in a single processor, analog functions can be implemented in the digital domain. This reduces the bill of material (BOM) costs and design cycle time and increases engineering flexibility.

Digital Signal Processing Solutions

Arm DSP instruction set extensions increase the DSP processing capability of Arm solutions in high-performance applications, while offering the low-power consumption required by portable, battery-powered devices.


Due to their flexibility, Arm DSP instructions touch a wide range of applications and industries. Take your smart assistant at home as an example: you say a command, and it recognizes your voice, processes what you’re saying and responds. This is an example of a multi-sensor device that requires signal processing.
