Digital Signal Processors

A digital signal processor is a specialized microprocessor (or a SIP block), with its architecture optimized for the operational needs of digital signal processing.

Digital signal processing (DSP) is the numerical manipulation of signals, usually with the intention to measure, filter, produce or compress continuous analog signals. It is characterized by the use of digital signals to represent these signals as discrete time, discrete frequency, or other discrete domain signals in the form of a sequence of numbers or symbols to permit the digital processing of these signals. The increasing use of computers has resulted in the increased use of, and need for, digital signal processing.
