Abstract
A single completion status write back is generated by a controller to inform a driver of completion of a transmission of all frames of an array of frames, as opposed to generating individual write backs for each frame. The driver identifies one of the frames that is reported with the completion status, and applies the completion status to that frame and to all frames of the array sent prior to that frame. Reducing the number of these overhead completion status write backs improves bus and data transfer efficiency.
