<p>PURPOSE:To improve the route selecting efficiency of the title circuit by outputting output data to the multistage switch network or by-pass circuit in accordance with the route selection decided result of the multistage network. CONSTITUTION:Data simultaneously inputted to a multistage switch network 11 is selected by a deciding circuit 21 when the data passes through the network 11 and properly route-selected data is outputted as a final output through a by-pass circuit 31. Erroneously route-selected data, on the other hand, is again subjected to route selection in another multistage switch network 12. The data is selected by a deciding circuit 22 and properly route-selected data is outputted as a final output through a by-pass circuit 32 and erroneously route-selected data is again subjected to route selection in a multistage switch network, 13. The data is selected at a deciding circuit 23 and properly route-selected data is outputted as a final output and erroneously route-selected data is discarded. When this circuit is used, the number of data inputted to the succeeding stages can be reduced.</p> |
