Abstract
A transaction management system is described for scheduling requests on an external bus. The system includes a number of queue registers to store requests and a controller coupled to queue registers to schedule external bus transactions for an agent that processes read requests, prefetch requests and write requests. The controller posts at least one write request to an external bus every defined number of transactions if at least one non-posted write request is stored in the queue registers.
