Method and apparatus for allocating bandwidth on a transmit channel of a bus

A processing system and method of communicating within the processing system is disclosed. The processing system may include a bus having a transmit channel, a receiving component, and a sending component configured to broadcast a payload to the receiving component over the transmit channel, interrupt the broadcast of the payload to signal a new bus operation to the receiving component over the transmit channel, and resume the broadcast of the payload over the transmit channel. The processing system may include an algorithm that prevents small payloads from being interrupted to initiate a new bus operation. The algorithm may also be used to limit the number of times a single write operation may be interrupted to initiate a new bus operation.
