Abstract: An agent is provided to include state table storage to hold a set of state tables to represent a plurality of coherence protocol actions, where the set of state tables is to include at least one nested state table. The agent further includes protocol logic associated with the state table storage, the protocol logic to receive a coherence protocol message, and determine a coherence protocol action of the plurality of coherence protocol actions from the set of state tables based at least in part on the coherence protocol message.

Abstract: A request is received that is to reference a first agent and to request a particular line of memory to be cached in an exclusive state. A snoop request is sent intended for one or more other agents. A snoop response is received that is to reference a second agent, the snoop response to include a writeback to memory of a modified cache line that is to correspond to the particular line of memory. A complete is sent to be addressed to the first agent, wherein the complete is to include data of the particular line of memory based on the writeback.
