Abstract
An apparatus includes a storage location and a write monitor circuit coupled to the storage location. The storage location is configured to store a write response indicator which is capable of indicating a reception of at least one write response. Each write response indicates that a corresponding write has reached a target device of that write. The write monitor circuit is configured to update the write response indicator in response to receiving an indication of a first write response. A computer accessible medium may comprises instructions which, when executed: (i) initialize the write response indicator; and (ii) issue one or more writes to a target device, wherein the target device is configured to response to each of the writes with a write response to be indicated by the write response indicator.
