Abstract

A controller is presented comprising one or more initiators coupled to one or more targets via a transaction bus and a corresponding number of data busses. The initiator(s) receive transaction requests from external logic, buffer the transaction and assign it a unique identifier, which is passed to an appropriate target via the transaction bus. The targets receive and queue the unique identifier until it can process the transaction, at which time it prompts the initiator to provide it the buffered transaction via a data bus dedicated to the target.
