摘要:
A processor may comprise a core area, a control unit, an uncore area. The core area may comprise multiple processing cores and line-fill buffers. A first processing core of the core area may store a first weakly ordered transaction in a first line-fill buffer. The firs processing core may offload the first weakly ordered transaction to the extended buffer space provisioned in the uncore area after receiving a request from the uncore area. The first processing core may then de-allocate the first line-fill buffer after the first weakly ordered transaction is offloaded to the extended buffer space. The uncore may then post the first weakly ordered transaction to a memory or a memory system. The control unit may track the first weakly ordered transaction to ensure that the first weakly ordered transaction is posted to the memory or the system.
