I/O descriptor cache for bus mastering I/O controllers |
摘要 |
One embodiment of the present invention provides a system that includes an I/O descriptor cache that is accessed by a bus mastering I/O controller. The I/O descriptor cache stores descriptors that describe data to be transferred during corresponding I/O operations. The system also includes an I/O controller configured to control one or more I/O devices. This I/O controller is configured to access I/O descriptors stored in the I/O descriptor cache without having to access the main memory, thereby conserving I/O bandwidth and power.
