To close, let's estimate the overall chip count required to add the multicast capability to a point-to-point network with 256 inputs and outputs. We will assume that for the chips that have little internal memory, we are constrained only by pin count, that each chip has 128 pins available for inputs and outputs and that the data paths are one bit wide. For the example con guration then, 32 chips are required for the concentrator, 16 for the adder, 6 for the dacs and 56 for the copy network… CONTINUE READING
