Abstract: A method and system of managing resources in a host bridge by determining whether resources are deficient, preventing a second device from obtaining further resources and if this measure does not enable a first device to obtain resources, guaranteeing all resources to the first device.

Abstract: An apparatus and method for predicting quantities of data required by requesting devices capable of requesting unspecified quantities of data from storage device, in which prediction of quantities that will be required are made based on past patterns of quantities of data required in past transfers.

Abstract: A circuit is provided that includes a bridge circuit for connecting a first bus to a second bus. The bridge circuit also includes a first bus interface coupled to the first bus and is adapted to receive a plurality of transactions from the first bus. Each transaction has an address targeting the second bus and data the length of which defines a transaction size. A request data engine for issuing requests on a second bus is also provided. The request data engine is capable of assigning a unique encoded header to data streams. Control logic is provided that is adapted to store a first portion of a first transaction of the plurality of transactions in a memory coupled between the first bus and the second bus. Management logic is provided that is adapted to manage multiple out-of-order data streams wherein the data streams may remain outstanding to the bridge circuit. Additionally, a method is provided that includes capturing a data stream request header. Determining which data stream a request is mapped into.
