A Percolation Data Migration Schema in a hybrid Cache Hierarchy

摘要

To reduce data fetching latency in multi-core processor, a new on-chip cache model, Percolation Cache Hierarchy (PCH) that is a hybrid combination of convention on-chip caches, and a new data migration schema, called Percolation Data Migration Schema (PDMS), for moving data massively on PCH to enrich hit possibility and reduce data moving latency, are introduced in this paper. Basing on the percolation data migration schema, a new on-chip data environment, Just In-Time Data Environment (JITDE), can be setup on the PCH to exploit the properties of data locality to increase hit rate.
