This section describes the overall data flow graph specification of the 2D-FFT design using AI Engine which is compiled by the AI Engine compiler.
The overall graph definition of the design is contained in the graph.cpp
file. The top-level graph contains two sub-graphs, FFTrows_graph
and FFTcols_graph
, each with a FFT_2D_INSTS
number of objects. The following describes the definition of the sub-graphs (the FFTrows_graph
is used as illustration).
