ABSTRACT:
Techniques for multiple master devices accessing one or more slave devices via a single data bus are disclosed. According to one aspect of the techniques, a bus controller coupled between the master devices and the slave device, wherein the bus controller is configured to receive bus signals from the master devices, select one of the bus signals from one of the master devices and forwards the selected bus signal to the slave device. After the slave device receives the bus signal from the one of the master devices, the slave device sends a bus response signal to the master devices over the bus controller, and the master device from which the bus signal is selected identifies and receives the bus response signal.
