Patent ID: 7317720

Claim:
A signal transmission system comprising: a master node; and a plurality of slave nodes for performing data transmission with the master node, wherein the master node includes a serial-to-parallel converter for converting a serial data signal from each of the slave nodes into a parallel data signal, and wherein each of the slave nodes includes a transmission aligner for performing word alignment processing upon a parallel data signal, and a parallel-to-serial converter for converting the parallel data signal subjected to the word alignment processing by the transmission aligner into a serial data signal, and outputting the serial data signal to the master node, and wherein the master node includes a master timing adjustment portion for executing a reception adjustment sequence and a transmission adjustment sequence during a period in which data transmission is not carried out, the reception adjustment sequence being provided for adjusting reception timing between a data signal and a synchronization signal outputted by the master node individually for each slave node, the transmission adjustment sequence being provided for adjusting transmission timing between a data signal and a synchronization signal outputted by each slave node individually for each slave node.
