Abstract
In one embodiment, the present invention includes a processor having at least one core and uncore logic. 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.
