Abstract:
1. A memory storage structure, comprising: at least one memory storage device; a first meta-structure having a first size and operating at a first speed, which is faster than a second speed for storing meta-information based on information stored in a memory; a second meta-structure hierarchically associated with the first meta-structure, the second meta-structure having a second size larger than the first size and operating at the second speed such that faster and more accurate prefetching is provided by coaction of the first and second meta-structures; and a meta-collector configured to collect and record look ahead context information in the meta-information which includes at least one of spatial and temporal state information associated with access of entries in a meta-structure and a memory location, such that the meta-collector provides prefetching of history table entries to the first meta-structure based upon the look ahead context information.
