Abstract

A bus interface unit is adapted to receive transaction requests for at least two different targets. The bus interface unit monitors a capacity of a resource associated with servicing transaction requests to the targets, such as a posted write buffer. If a transaction request would fill the resource beyond a current remaining capacity of the resource such that the execution of other pipelined transactions would become stalled, the bus interface generates a retry response so that the request is retried at a later time, permitting other transactions to proceed while the resource drains.
