An embodiment of the invention is a bridge having a transaction queue for storing transaction information for each of a number of enqueued posted write transactions, a data queue for simultaneously storing transaction data for each of the enqueued transactions, the transaction data having been received through slave logic of the bridge to be delivered through master logic of the bridge, and a controller for managing the transaction and data queues in response to the transaction information, the bridge being further configured to dynamically allow the transaction data for a single enqueued transaction to occupy the maximum available space in the data queue.
