Abstract
The present disclosure is directed to hardware hash tables, and more specifically, to generation of a cache coherent system such as in a Network on Chip (NoC). The present disclosure is further directed to a directory structure that includes a new field, referred to, for instance as, encoded value, which indicates the original owner of a dirty line. As an original holder may have held or modified the original line, by tracking the original holder, example implementations can track the agents that are potentially dirty, as the encoded value can indicate the agent with the most recently unique line, which can then be shared with the other agents.
