(Acronym "DSP") A special type of computer processor IC, optimized for doing the math involved in generating and processing signals and waveforms in a digital representation. DSPs are frequently used in digital synthesizers to do the processing functions, and in samplers to implement pitch shift and filter capabilities.

DSPs generally operate under the control of a CPU, running a software program that instructs the DSPs as to what operations they are to perform at a given time. Some recent digital synth designs employ a concept called DSP flex, in which the operating system reassigns DSPs to different functions on the fly.
