ACML FFT SIMD

Does the ACML FFT take advantage of SIMD instructions? If it does, why doesn't the input array memory need to be SIMD aligned? In order for FFTW to use SIMD, the input array must be SIMD aligned in memory via the fftw_malloc function: http://www.fftw.org/doc/SIMD-alignment-and-fftw_005fmalloc.html.
