- An on-chip memory hierarchy organization for a multicore processing system is disclosed. The hierarchy supports virtual- addressed private caches and a physical-addressed shared cache. The hierarchy classifies cache line data as private or shared to support a one-directional request response protocol. The classification can be determined from the generational behavior of a cache line in the private caches. Cache lines having a single generation in a private cache are Private, and cache lines having overlapping generations in two or more private caches are Shared. The Private or Shared classification is performed dynamically at run-time in hardware using a single translation lookaside buffer at the interface between the private and shared caches. The coherence protocol uses the data classification in a dynamic write policy for both shared data race free data and private data, differentiating in when data is put back to the shared cache based on the classification.
