Abstract:
Systems and methods are disclosed for reducing power consumed by capturing data from an I/O device. Techniques disclosed include receiving descriptors, by a controller of an I/O host of a system, including information associated with respective data chunks to be captured from an I/O device buffer of the I/O device. Techniques disclosed further include capturing, based on the descriptors, the data chunks. The capturing comprises pulling the data chunks from the I/O device buffer at a pulling rate, where the data chunks are transferred to a local buffer of the I/O host, and pushing segments of the pulled data chunks from the local buffer, where each segment is transferred to a data buffer of the system after a respective target time that precedes a time at which the data chunks in the segment are to be processed by an application executing on the system.
