ADSP-21xxx SHARC
SHARC DSP Radio Library
- A set of DSP Radio Library functions
implemented on the ADSP-21xxx SHARC 32-bit floating point DSP, which performs DSP
demodulation on baseband IQ components and FIR Filtering
operations on audio and speech signals. The filtering is aimed at
filtering the demodulated audio (e.g. from short-wave receivers)
to improve the clarity of reception. Different filtering modes
are aimed at Speech (Single Side Band, SSB, NBFM), Music
(Amplitude Modulation, AM), Morse Code (Continuous Wave, CW) and
Data (AM). The 32-bit floating-point DSP allows filtering with a
-100 dB minimum stopband, a figure unobtainable from 16-bit
fixed-point DSPs.
- The DSP Radio Library is supplied with
documentation and DSP example code. The full DSP source code is
available.
