The ADSP-2171, ADSP-2172, and ADSP-2173 are single chip microcomputers optimized for digital signal processing (DSP) and other high-speed numeric processing operations. The first of this family was the ADSp-2171 (Analog Dialogue 28-1, 1994); it is being used for such applications as algorithm signal-processing for speech coding and soft-decision equalizing in GSM baseband processing—as well as low-delay code-excited linear prediction (LD-CELP), echo cancellation, and call processing for telephony.
