Abstract
A system comprises a first processor having cache memory, a second processor having cache memory and a coherence buffer that can be enabled and disabled by the first processor. The system also comprises a memory subsystem coupled to the first and second processors. For a write transaction originating from the first processor, the first processor enables the second processor's coherence buffer, and information associated with the first processor's write transaction is stored in the second processor's coherence buffer to maintain data coherency between the first and second processors.
