摘要： Embodiments of the present invention provide a system that schedules the transfer of cells in a switch. The system starts by receiving a set of cells to be transferred from a set of inputs of the switch to a set of outputs of the switch. The system includes S subschedulers, wherein each subscheduler processes N scheduling waves in sequence to generate a conflict-free transfer schedule for a given time slot for a matrix of transfer elements in the switch. The system then operates the subschedulers in parallel to generate S transfer schedules to transfer the cells from the set of inputs of the switch to the set of outputs of the switch during S time slots.

摘要： Embodiments of the present invention provide a system that transfers data between the components in the computer system through a switch. In these embodiments, the switch includes multiple switch chips which are coupled together and are configured to collectively function as a switch. During operation, each switch chip, receives cells from the subset of the set of inputs and selectively transfers each of the cells to at least one output of the subset of the set of outputs coupled to the switch chip or of the subset of the set of outputs coupled to the other switch chips.

摘要： Embodiments of a scheduler for a switch, where the switch is configured to couple input ports to output ports are described. During operation, the scheduler may determine a schedule based on a group of requests, associated with multiple data streams, that are received for the output ports of the switch, where the schedule matches input ports to output ports of the switch for a given data cell time. Note that the schedule may be determined using an arbitration technique during a time interval. Moreover, the scheduler may assign an additional request, which was received at a time that precedes a current time by less than the time interval, to a portion of the switch which is available in the schedule, thereby reducing a latency of the scheduler.

摘要： A switch contains a first semiconductor die, which is configured to receive signals on a plurality of input ports and to output the signals on a plurality of output ports. The first semiconductor die is further configured to selectively couple the signals between the input and output ports using a plurality of switching elements in accordance with a set of control signals, which correspond to a configuration of the switch. During this process, a plurality of proximity connectors, proximate to a surface of the semiconductor die, are configured to communicate the signals by capacitive coupling.
