System, apparatus and method for granting access to a shared communications bus |
摘要 |
Systems, apparatuses and methods for timing access to a shared communications bus by a plurality of devices. Each of a plurality of nodes is successively provided an opportunity to gain access to a shared bus according to a time slot allocation referenced from a time reference. The successive time slot allocation occurs until one of the nodes has a message to send via the shared bus. The node that has the message to send transmits a frame onto the bus. A new time reference is established at each of the nodes based on an indication provided by the transmitted frame, whereby each of the nodes can then be afforded a new opportunity to gain access to the shared bus according to the time slot allocation referenced from the new time reference. |
