A method is provided for requesting data from a memory. The method includes issuing a plurality of data requests to a data request port for the memory. The plurality of data requests includes at least two ordered data requests. The method includes determining if an earlier one of the ordered data requests corresponds to a miss in the memory, and converting a later one of the ordered data requests to a prefetch in response to the earlier one of the ordered data requests corresponding to a miss in the memory. An apparatus includes a memory having at least one pipelined port for receiving data requests. The port is adapted to determine whether an earlier ordered one of the data requests corresponds to a miss in the memory. The port converts a later ordered one of the data requests to a prefetch in response to determining that the earlier ordered one of the data requests corresponds to a miss in the memory. |
