MEMORY ACCESS LATENCY HIDING WITH HINT BUFFER

摘要

A request hint is issued prior to or while identifying whether requested data and/or one or more instructions are in a first memory. A second memory is accessed to fetch data and/or one or more instructions in response to the request hint. The data and/or instruction(s) accessed from the second memory are stored in a buffer. If the requested data and/or instruction(s) are not in the first memory, the data and/or instruction(s) are returned from the buffer.
