The filter identifies whether the current block was last accessed as a data or as an instruction. With this information, looking up the whole directory can be ...
We propose two filter implementations that are accessed before the directory. These filters dismiss lookups that would “miss” in the directory. All proposed ...
Abstract—Coherence protocols consume an important frac- tion of power to determine which coherence action should take place. In this paper we focus on CMPs ...
In this paper, we focus on CMPs using write-through local caches, and a directory-based coherence protocol implemented as a duplicate of the local cache tags. A ...

This filter reduces significantly the number of directory lookups performed (Chapter 3). The second filtering mechanism tries to identify which processors have ...
This paper proposes to add a filter before the directory lookup in order to reduce the number of lookups to this structure and shows that a filter with a ...
