DOCUMENTATION ABOUT NEW FFT CODES RUN WITH THE 320C3x
-----------------------------------------------------
Attached to this Readme file you will find four FFT codes :
FORFFT.asm is a radix-2 real forward FFT,
INVFFT.asm is a radix-2 real inverse FFT,
R2DIT.asm is a radix-2 complex forward FFT,
R2IDIT.asm is a radix-2 complex inverse FFT.
These codes are either new or improved existing code, and they are
C callable functions.
For instance the real forward FFT function can be called with the six
following arguments : size of FFT, log size of FFT, location of FFT input data,
location of FFT output data, location of sin/cos table, bit-reversing enable.
To make it clearer and easier to use, examples of C programs which call
these FFT codes are provided also here. They are called :
FORFFTC.c for the radix-2 real forward FFT,
INVFFTC.c for the radix-2 real inverse FFT,
R2DITC.c for the radix-2 complex forward FFT,
R2IDITC.c for the radix-2 complex inverse FFT.
Link command files are also provided to show memory allocation of code and
data sections when the programs are run on the C3x EVM ( the FFT programs
can be run on the C3x simulator or emulator after checking memory allocation).
These link command files are called :
FORFFT.cmd for the radix-2 real forward FFT,
INVFFT.cmd for the radix-2 real inverse FFT,
R2DIT.cmd for the radix-2 complex forward FFT,
R2IDIT.cmd for the radix-2 complex inverse FFT.
In the case of the complex FFT algorithms, the sin/cos table must be arranged
in bit-reverse order.
BITREV.asm is doing it.
The .asm and .c files were compiled with cl30 ( no option) command of
the rev 4.4. C30 C compiler.
