The mixed_radix_fft supports AIE and AIE-ML devices.

All features are supported on these variants with minor differences as follows:

  • TP_POINT_SIZE: The width of vectors used for calculations differs by AIE variant. The point size TP_POINT_SIZE must be a multiple of the number of samples processed in an atomic vectorized butterfly operation. This is 16 for AIE and 32 for AIE-ML.
  • TP_RND: Supported round modes differ between AIE and AIE-ML devices 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. AIE-ML accepts one stream only.
  • TP_DYN_PT_SIZE: the dynamic (run-time) point-size feature is supported on AIE only.
