This routine computes a complex forward mixed radix FFT with rounding and digit reversal. Input data x[ ], output data y[ ], and coefficients w[ ] are 16-bit. The output is returned in the separate array y[ ] in normal order. Each complex value is stored with interleaved imaginary and real parts.
ptr_w | = input twiddle factors | |
npoints | = number of points | |
ptr_x | = transformed data reversed | |
ptr_y | = linear transformed data |
