specialized microprocessor optimized for digital signal processing in real time, mainly used for audio and/or video applications
This article is about Digital signal processor. For Digital signal processing, see Digital signal processing.

A digital signal processor (DSP or DSP micro) is a specialized microprocessor designed specifically for digital signal processing, generally used in real-time computing.[1]

A simple digital processing system, ADC converts analog signal to digital, then DAC returns it back to analog format after processing

Digital signal processing algorithms require a large number of mathematical operations to be performed quickly on a set of data. Signals are converted from analog to digital, manipulated digitally, and then converted again to form digital to analog, as shown in the diagram. Many digital signal processing applications have real-time constraints; that is, for the system to work, the DSP operation must be completed within some time limit.

The microarchitecture of a digital signal processor is optimized specifically for digital signal processing applications.
