Abstract: A bus architecture is disclosed that provides for transaction queue reallocation on the modules communicating using the bus. A module can implement a transaction request queue by virtue of digital electronic circuitry, e.g., hardware or software or a combination of both. Some bus clogging issues that affect conventional systems can be circumvented by combining an out of order system bus protocol that uses a transaction request replay mechanism. Modules can evict less urgent transactions from transaction request queues to make room to insert more urgent transactions. Master modules can dynamically update a quality of service (QoS) value for a transaction while the transaction is still pending.
