Input Switch Matrix
The input switch matrix (Figures 12 and 13) optimizes routing of inputs to the central switch matrix.
Without the input switch matrix, each input and feedback signal has only one way to enter the central switch
matrix. The input switch matrix provides additional ways for these signals to enter the central switch matrix.
