摘要： Embodiments of the invention utilize a universal serial bus (USB) host controller to traverse an asynchronous data transfer list to identify data transfers to execute. The asynchronous data transfer list may include a plurality of header nodes, each header node to identify data transfers to one of a plurality of devices operatively coupled to an electronic device. The USB host controller may execute an extended sleep mode in response to identifying no data transfers to execute and receiving an indication that the system processor is in a sleep state. The USB host controller may exit the extended sleep mode in response to receiving an indication that the processor is in non-sleep state.

摘要： An apparatus may include a processor and first logic operable on the processor to output a direct memory access (DMA) activity indicator to indicate a current state of activity of direct memory access data transfer operations. The apparatus may further include second logic operable on the processor to determine scheduled DMA activity to be performed; and third logic operable on the processor to output a pre-wake indicator to a controller before the scheduled DMA activity is to be performed, to satisfy both Quality of Service (QOS) and Power saving needs. Other embodiments are disclosed and claimed.

摘要： A method, device, system, and computer readable medium are disclosed. In one embodiment the method includes dynamically associating a newly active port in a computer system with a first host controller. The first association happens when a total number of currently active ports in the computer system is less than a maximum capacity number of ports for the first host controller. The method also includes dynamically associating the newly active port in the computer system with a second host controller. The second association happens when the total number of currently active ports in the computer system is greater than or equal to the maximum capacity number of ports for the first host controller. In this method, each port, the first host controller, and second host controller all utilize the same protocol.
