3.4.2. Variable Streaming

The variable streaming FFT allows continuous streaming of input data and produces a continuous stream of output data similar to the streaming FFT. With the variable streaming FFT, the transform length represents the maximum transform length. You can perform all transforms of length 2m where 6 < m < log2(transform length) at runtime.
