Abstract:
The size of a cache is modestly increased so that a short pointer to a predicted next memory address in the same cache is added to each cache line in the cache. In response to a cache hit, the predicted next memory address identified by the short pointer in the cache line of the hit along with an associated entry are pushed to a next faster cache when a valid short pointer to the predicted next memory address is present in the cache line of the hit.
