Abstract
An input/output bridge controls access to a memory by a number of devices. The bridge enforces ordering of access requests according to a register storing an order configuration, which can be programmed to accommodate a given application. When suspending an access request as a result of enforcing an order configuration, the bridge may also cause a prefetch at the memory for the suspended access request. Subsequently, following the completion of a previous access request meeting the order configuration, the suspended access request is released. Due to the prefetch, an access operation can be completed with minimal delay.
