The data type to the FFT window is controlled by the TT_DATA template parameter . This can take one of three choices: cint16, cint32, or cfloat (AI Engine (AIE) only, not AIE-ML). This selection applies to both input data and output data.
The TT_COEFF template parameter can 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.
