Hi Nilay, Thanks for your guidance, could you please also let us know if there is an difference between the DMA sequencer and memory controller in Ruby? Also, I can't figure out how many memory controllers do we have in Mesh topology and MeshDirCorners topology. >From what I understood from the code (Mesh.py) is that the DMA controller is connected to remainder nodes (not sure what that is), also is it that there is just one shared memory and multiple memory controllers connected to it or there are multiple SDRAMs connected to memory controllers. Please throw some light on this. I really appreciate your help.
