ABSTRACT:
A method for delayed memory access request arbitration includes dispatching a first memory access request to a memory controller and dispatching a second memory access request to the memory controller in response to an anticipated completion of a memory access operation represented by the first memory access request. Another method includes receiving a first memory access request at a bus interface unit at a first time, dispatching a second memory access request to a memory controller at a second time subsequent to the first time, receiving a third memory access request at the bus interface unit at a third time subsequent to the second time, dispatching the third memory access request to the memory controller at a fourth time subsequent to the third time and dispatching the first memory access request to the memory controller at a fifth time subsequent to the fourth time.
