The data type to the FFT window is controlled by the template parameter TT_DATA. This may take one of 3 choices: cint16, cint32 or cfloat (AIE only, not AIE-ML). This selection applies to both input data and output data.
The template parameter TT_COEFF may take one of three values, int16, int32 or cfloat, but currently this value is forced by the choice of TT_DATA, so TT_COEFF must be set to:
- int16 when
TT_DATAis set to cint16 or - int32 when
TT_DATAis set to cint32 or - float for
TT_DATAset to cfloat.
