Abstract

In accordance with the described techniques for condensed coherence directory entries for processing in memory, a computing device includes a core that includes a cache, a memory that includes multiple banks, a coherence directory that includes a condensed entry indicating that data associated with a memory address and the multiple banks is not stored in the cache, and a cache coherence controller. The cache coherence controller receives a processing-in-memory command to the memory address and performs a single lookup in the coherence directory for the processing-in-memory command based on inclusion of the condensed entry in the coherence directory.
