22. Ifft_q31_time_128points

22.1. Function description:

This demo shows the transformation of IFFT Q31 in time domain with 128 points.

Configure Q31 time domain inverse transformation with 128 points:

• Initialize & configure the FFT, the input data means is RIRI.

• Set the address of TF & input data, then loading and start calculation.

• Waiting calculation done to compare the result with the golden data to check.

Note

The golden data just fit for the RTL cofiguration: FFT Max point is 4096.

22.2. Test result:

If the output result is same as the golden data, then print pass, if not print fail.

22.3. IO connection:

None
