The m2s_x2 is generated from the kernel/spec.json specification. Review this file. Notice the m2s_x2 kernel implementation is set to LoadDdrToStream, meaning this kernel is used to move data from DDR (AXI-MM) to AXI-Stream. It is specified to have two channels. The first channel moves data from a DDR buffer called ibuff to an AXI-stream called istrm. This channel moves the i data out of DDR to AXI-Stream. The second channel moves j data from DDR buffer jbuff to an AXI-Stream jstrm and streams the data directly into the AI Engine’s input_j port.
