1. A method for processing memory access instructions in a computer which includes a memory, the method comprising: receiving a first memory access instruction which represents a first access of data within the memory at a first range of memory addresses; determining that the first memory access instruction is incomplete; storing the first memory access instruction in a sideline buffer; receiving a second memory access instruction which represents a second access of data within the memory at a second range of memory addresses; processing the second memory access instruction to effect the second access of data within the memory at the second range of memory addresses further comprises: determining whether the first and second ranges of memory addresses share one or more common memory addresses; upon a condition in which the first and second ranges of memory addresses share one or more memory addresses, postponing the step of processing the second memory access instruction until after performance of the step of processing the first memory access instruction; and upon a condition in which the first and second ranges of memory addresses share no common memory addresses, performing thy step of processing the second memory a access instruction prior to performance of the step of processing the first memory access instruction; subsequent to receiving the second memory access instruction, receiving data which completes the first memory access instruction; combining the received data with the first memory access instruction to form a complete memory access instruction; and processing the complete memory access instruction to effect the first access of data within the memory at the first range of memory addresses.
