nd then pass one of the constant structures as an argument to arm_cfft_f32. For example: </dd></dl>
<dl class="section user"><dt></dt><dd><code>arm_cfft_f32(arm_cfft_sR_f32_len64, pSrc, 1, 1)</code> </dd></dl>
<dl class="section user"><dt></dt><dd>computes a 64-point inverse complex FFT including bit reversal. The data structures are treated as constant data and not modified during the calculation. The same data structure can be reused for multiple transforms including mixing forward and inverse transforms.
