The fft_ifft_dit_1ch supports AIE and AIE-ML devices. All features are supported on these variants with the following differences:

  • TT_DATA and TT_TWIDDLE. AIE-ML does not support cfloat type.
  • TT_TWIDDLE: AIE supports cint32. AIE-ML does not.
  • TP_RND: Supported round modes differ between AIE and AIE-ML as for all library elements.
  • Number of ports: When configured for TP_API=1 (stream IO), AIE will require 2 input ports (sample interleaved - even samples on the first port) and 2 output ports similarly interleaved for each lane of processing. The number of lanes is 2^TP_PARALLEL_FACTOR. AIE-ML accepts one stream only per kernel.
