The sc switch defines connections between the ports of the AI Engine graph and the streaming ports of PL kernels. The first set of sc connections are between the dlbf_data PL kernel instances and the AI Engine dlbfid (input data) ports. The next set of connections are between the dlbf_coeffs PL kernels and the AI Engine dlbfic (input coefficient) ports. The AI Engine ports are connected to the PL kernels’ M00_AXIS (master AXI4-Stream) ports.

The next connections are between the AI Engine dlbfo (output) ports and the dlbf_slave instances. The AI Engine ports are connected to the PL kernels’ S_AXIS (slave AXI4-Stream) ports.

The config.ini file repeats this connection scheme for all three instances of the DLBF system and for all three ULBF systems as well.
