A transmission circuit for transmitting data from a host to a remote includes a plurality of memory queues, and a memory controller operable to prefetch a burst of data cells from the host, wherein a first data cell of the burst is transmitted by the memory controller to the remote and the remainder of the data cells of the burst are stored in the plurality of memory queues for later transmission to the remote.

System and method for prefetching data

A method of scheduling transmission of a plurality of cells of a first signal packet associated with a first virtual channel address using a scheduling ring having a plurality of slots and pointer operable to indicate a current slot includes advancing the pointer to a slot associated with the first virtual channel address, initiating transmission of a previously scheduled first cell associated with the first virtual channel address, rescheduling transmission of a previously unscheduled second cell associated with the first virtual channel address for transmission at a later time, and advancing the pointer to the next slot.

System and method for traffic shaping packet-based signals

A data transmission system includes a memory, a remote coupled to the memory by a receive data controller, and a host coupled to the memory by a transmit data controller. The system prioritizes the transmission of data cells from the remote to the host based on demand by dynamically allocating portions of the memory to data cells sharing a common and frequently recurring address at the host, and transmitting to the host incihvidual data cells together in a burst.
