The fftRow
function is defined in the following example:
#if FFT_2D_DT == 0 // cint16 datatype
void fftRow(
bool direction,
cmpxDataIn in[MAT_COLS],
cmpxDataOut out[MAT_COLS],
bool* ovflo)
#else // cfloat datatype
void fftRow(
bool direction,
cmpxDataIn in[MAT_COLS],
cmpxDataOut out[MAT_COLS])
#endif
{
#pragma HLS dataflow
configRow_t fft_config;
statusRow_t fft_status;
cmpxDataOut inp_fft[MAT_COLS];
#pragma HLS STREAM variable=inp_fft depth=2
cmpxDataOut out_fft[MAT_COLS];
#pragma HLS STREAM variable=out_fft depth=2
fftRow_init(direction, &fft_config);
// FFT IP
//copyRow_inp(in, inp_fft);
//hls::fft<configRow>(inp_fft, out_fft, &fft_status, &fft_config);
//copyRow_out(out_fft, out);
hls::fft<configRow>(in, out, &fft_status, &fft_config);
#if FFT_2D_DT == 0 // cint16 datatype
fftRow_status(&fft_status, ovflo);
#endif
