Abstract

See full text

An information handling system, method, and processor that detects a store instruction for data in a processor where the store instruction is a reliable indicator of a future load for the data; in response to detecting the store instruction, sends a prefetch request to memory for an entire cache line containing the data referenced in the store instruction, and preferably only the single cache line containing the data; and receives, in response to the prefetch request, the entire cache line containing the data referenced in the store instruction.
