CROSSBAR NETWORK DEVICE ADOPTING LOCAL CONTROL

PURPOSE:To perform the arithmetic processing at a high speed by providing a logic circuit at each cross point in a network to decide whether the output should be applied to the input or not. CONSTITUTION:In a crossbar network 10, the signal lines 14 - 16 connected with the storages 11 - 13 along a horizontal axis are orderly arranged toward the lower side from the upper side in a diagram. Meanwhile the signal lines 20 - 22 connected with the microprocessors 17 - 19 along a vertical axis are orderly arranged toward the right side from the left side in the diagram respectively. These signal lines cross to each other at codes 26 - 34 which mean the cross points where the signal lines cross to each other. A logic circuit 23 containing a crossbar switch is provided at each cross point. The circuit 23 decides the propriety for connection of input and output lines according to the coincidence or discordance between the input and output signals. Thus the arithmetic processing is carried out at a high speed.
