METHOD AND APPARATUS FOR PRE-FETCHING DATA IN A SYSTEM HAVING A MULTI-LEVEL SYSTEM MEMORY

摘要

A method is described that includes creating a first data pattern access record for a region of system memory in response to a cache miss at a host side cache for a first memory access request. The first memory access request specifies an address within the region of system memory. The method includes fetching a previously existing data access pattern record for the region from the system memory in response to the cache miss. The previously existing data access pattern record identifies blocks of data within the region that have been previously accessed. The method includes pre-fetching the blocks from the system memory and storing the blocks in the cache.

1. A method, comprising:
creating a first data pattern access record for a region of system memory in response to a cache miss at a host side cache for a first memory access request, the first memory access request specifying an address within the region of system memory; fetching a previously existing data access pattern record for the region from the system memory in response to the cache miss, the previously existing data access pattern record identifying blocks of data within the region that have been previously accessed; and pre-fetching the blocks from the system memory and storing the blocks in the cache.
