Abstract
An information handling system transfers data blocks between a host processing side having a CPU and a host memory and a local processing side having a local processing unit and a local memory. The local memory includes a DCB queue memory portion having a plurality of DCB images each image defining host and local addresses of a corresponding data transfer. The DCB images also store a default status condition representing the most likely condition of a data transfer which in the preferred embodiment is a no error condition. A data transfer status detector determines whether the default status condition is true or false. If true, the default status information relating to a corresponding data block transfer is posted on the host processing side without local processing unit intervention.
