DSP: what it means.
Digital signal processing applies computation to signals represented digitally, such as audio or sensor data. Arm describes both dedicated DSP hardware and instruction-set extensions that let a processor perform signal-processing work. (Arm: digital signal processing)
A document saying that a device supports DSP does not necessarily identify a separate DSP chip. It may refer to algorithms, arithmetic instructions or an integrated engine. Determine which meaning applies before comparing architectures. (Arm: digital signal processing)
Put the definition to work.
Audio, voice, and sensor applications are useful places to encounter DSP. Check whether the document means a signal-processing technique, a dedicated processor, or instruction-set extensions. (Arm: digital signal processing)
Questions to ask next.
Use these questions as a reading checklist, not as a device-selection recommendation. Exact manufacturer documentation takes priority over a general definition.
- Technique versus hardware meaning
- Supported operations and software
- Signal rates and application timing

Common DSP questions.
Can a CPU perform DSP?
Yes. Arm describes DSP extensions that let a processor run control code and signal-processing operations together. Dedicated DSP hardware is another implementation option. (Arm: digital signal processing)
