Abstract
A method and system for flexible prefetching of data and/or instructions for applications are described. A prefetching mechanism monitors program instructions and tag information associated with the instructions. The tag information is used to determine when a prefetch operation is desirable. The prefetching mechanism then requests data and/or instructions. Furthermore, the prefetching mechanism determines when entry into a different execution phase of an application program occurs, and executes a different prefetching policy based on the application's program instructions and tag information for that execution phase as well as profile information from previous executions of the application in that execution phase.
