Abstract
A processing system includes a processing device and a host processor operatively coupled to the processing device via a system bus, and implements a scatter gather data transfer technique. The host processor is configurable to control the transfer of information to or from scattered or non-contiguous memory locations in a memory associated with the processing device, utilizing a data structure comprising a single descriptor. An information transfer bandwidth of the system bus is thereby more efficiently utilized than if a separate descriptor were used for transfer of information involving each of the non-contiguous memory locations.
