  • Patent number: 9189161
    Abstract: A system for performing a scatter-gather data transfer operation. The system includes a shifter configured to selectively receive, based on a selection signal, one of first data input to the system and second data input to the system prior to the first data being input to the system, perform, based on a shift signal, a shift operation on the one of the first data and the second data received by the shifter, and output first shifted data resulting from the shift operation. A controller is configured to receive a first indication of a start byte location of the first data input to the system, receive a second indication of a length of the first data input to the system, and output, based on the first indication and the second indication, the shift signal. The shift signal indicates to the shifter when to perform the shift operation.
