<p>PURPOSE: To prevent the delay of a packet and to evade occurrence of collision by constituting a space divided multiplex exchange circuit of elements having an exchange point stage followed by a comparator, an input buffer, a determination circuit, and a clock signal control circuit. CONSTITUTION: This exchange circuit is constructed by elements having the same constitution so that each switched circuit is divided into each stage. These elements have the stage of an exchange point CP followed by a comparator C, an input buffer B, a determination circuit CA, and a clock signal control circuit T respectively allocated to the elements. The circuit CA connected to both the comparator C and exchange point CP determines the order of feed lines Z arrayed in each line to be exchanged.</p> |
