Digital Signal Processor (DSP)

Digital Signal Processor (DSP)- Definition

A digital signal processor (DSP) is a specialized microprocessor designed specifically for digital signal processing, generally in real-time computing. The DSP processes digital signals converted (using an Analog-to-digital converter (ADC)) from analog signals. Output is then converted back to analog form using a Digital-to-analog converter (DAC).

VoIP DSPs are application specific DSPs, designed to convert analog voice to digital voice over IP. VoIP DSPs support the necessary protocols and features required for VoIP streaming including the implementation of different VoIP CODECs (Coders – Decoders) such as: G.711, G.723, GSM etc., the implementation of Real Time Protocol (RTP) and an IP stack.
