Abstract:
1. A device comprising: a bus that comprises multiple bus lines; a bus transmitter circuit coupled between an information source and the bus; a bus receiver circuit coupled between the bus and an information target; wherein the information source and the information target are mutually asynchronous; a bus receiver control circuit that controls the bus receiver circuit and a bus transmitter control circuit that controls the bus transmitter circuit; wherein the bus transmitter control circuit enables the bus transmitter circuit to transmit information from the information source to the bus in response to a change in a value of a feedback signal sent from the bus receiver control circuit; and wherein the bus receiver control circuit enables the bus receiver circuit to provide information from the bus to the information target in response to a change in a value of a delayed strobe signal provided by a delay unit coupled between the bus receiver control circuit and the bus transmitter control circuit; and wherein the bus transmitter control circuit sends a strobe signal to a delay unit that provides a delayed strobe signal to the receiver control circuit; and wherein a delay period of the delay unit is substantially equal to a maximal delay period introduced by lines of the bus.
