Abstract
A matrix chip having N inputs, M outputs and a number of crosspoint switches, preferably N×M crosspoint switches. The crosspoint switches form a switching matrix that connects the inputs and outputs so that any input is randomly connectable to any output. In order to minimize the signal path lengths on the chip, the inputs and outputs are arranged on the matrix chip in the shape of a cross dividing the matrix into four sectors.
