The goal of DSP is usually to measure, filter or compress continuous real-world. Most general-purpose microprocessors can also execute digital signal processing algorithms successfully, but may not be able to keep up with such processing continuously in real-time.

DSPs often use special that are able to fetch multiple data or instructions at the same time. A typical digital processing system Digital signal processing typically require a large number of mathematical operations to be performed quickly and repeatedly on a series of data samples.
Signals (perhaps from audio or video sensors) are constantly converted from analog to digital, manipulated digitally, and then converted back to analog form. Many DSP applications have constraints on; that is, for the system to work, the DSP operation must be completed within some fixed time, and deferred (or batch) processing is not viable. Most general-purpose microprocessors and operating systems can execute DSP algorithms successfully, but are not suitable for use in portable devices such as mobile phones and PDAs because of power efficiency constraints.
