dsp AD公司ADSP21的代码,里面有FFT FIR IIR EQULIZER G722_21F 等可以在项目中直接应用的代码.此代码的来源是ADI公司自己出版的书籍,此书在美国购得

README FILE FOR TI C30 PROCESSORS
---------------------------------

These files for TI's C30 DSP processor were compiled using TI's
C30/C40 compiler version 4.50.  The programs were tested on a
33 MHz C31 processor board (called the DSPCard-C31) made by
Domain Technologies, Inc. (Plano, TX).

The batch files (*.BAT) will compile and load the programs.

The make files (*.MAK) will compile the programs which have
changed and load the program if you have a MAKE utility.  If you
get "OUT MEMORY" errors from the compiler, you may have to use
the batch files because of DOS memory limitations.

The name of the LNK30 output DSP executables have a ".OUT"
extension.

REAL-TIME PROGRAM NOTES
-----------------------

The following describes the real-time aspects of the programs in
this directory:

 Make File     Executable
   Name        File Name
------------  ------------
EQ.MAK        EQUALIZ.OUT    Change EQ settings by changing the 7 element
                             _gain array. gain[0] is lowest frequency and
                             gain[6] is the highest frequency band. A value
                             of 3 in gain will cause a boost of 12 dB.

G722C3F.MAK   G722MAF.OUT    Floating-point version.  Encodes and decodes
                             "chicken little" and then requires a real-time
                             input for encode/decode.

G722C3.MAK    G722MAIN.OUT   Fixed-point version.  Encodes and decodes
                             "chicken little" and then requires a real-time
                             input for encode/decode.

MKGWN.MAK     MKGWN.OUT      Noise filtering with sine wave example.
                             Filter turns on and off every second.

MUC3.MAK      MUC3.OUT       Plays a 6 voice song.

MULAW.MAK     MULAW.OUT      Encodes and decodes G711 (mu-law) speech
                             compression.  Setting _bypass to 1 will
                             pass the signal without compression.  Requires
                             a real-time input for encode/decode.

OSC.MAK       OSC.OUT        Plays a tone which drops in frequency.

PS.MAK        PSHIFT.OUT     Pitch shift using poly-phase filter.  Requires
                             a real-time input.  Every 4 seconds the pitch
                             shift key increases one semi-tone from -6 to 12.

RFC30.MAK     RFAST30.OUT    FFT based filtering; requires a real-time input.
                             Filter turns on and off every second.

WAVETAB.MAK   WAVETAB.OUT    Wave table music synthesis. Plays a scale from
                             key -12 to 47.
