The uncore logic can include a home agent to act as a guard to control access to a memory region. Either in the home agent or another portion of the uncore logic, a directory cache may be provided to store ownership information for a portion of the memory region owned by an agent coupled to the processor. In this way, when an access request for the memory region misses in the directory cache, a memory transaction can be avoided. Other embodiments are described and claimed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Providing a directory cache for peripheral devices","description":"In one embodiment, the present invention includes a processor having at least one core and uncore logic.
