This section describes the overall data flow graph specification of the 2D-FFT design using AI Engine, 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 an FFT_2D_INSTS number of objects. The following describes the definition of the sub-graphs (the FFTrows_graph is used as an illustration).
