A system may comprise multiple master/slave devices coupled to a common bus, where one of the devices may operate as the current master device and the other devices may operate as current slave devices. Current slave devices may embed bus ownership request information within response packets transmitted in response to standard bus operations, such as reads and writes, issued by the current master device. When the current master device is idle, its bus interface may continually poll the current slave devices at regular intervals, according to a specified protocol, to ascertain whether any of them are requesting bus ownership. A response to a request for bus ownership received by the current master device may be configured according to desired system functionality. In one system, ownership may always be transferred to the requesting device. In other systems, the current master device may transmit a subsequent standard bus operation request packet, or a unique response packet, either comprising embedded information indicating whether ownership of the bus has been granted.
