ABSTRACT:
A bus system uses separate clocks for arbitration and data transfer. The arbitration clock signal is used for synchronizing bus request and grant events, and the data clock signal is used for synchronizing data transmission and reception. In particular, the data clock signal, which is generated by a bus master node without any temporal relationship to the arbitration clock signal, is transmitted by the bus master node through the bus to a slave node, where the received data signal is synchronized with the data clock signal transmitted therewith.
