摘要：
Direct memory access is provided for each member of a group of IO devices organized into groups. Direct memory access for each IO device is performed in a predetermined order based on the predetermined groups, and may be completed by notification by an interrupt request. A predetermined time delay may be specified between each memory access by each IO device of a predetermined group.
