System method for managing USB data transfers by sorting a plurality of endpoints in scheduling queue in descending order based partially on endpoint frequency

摘要

System and methods are provided for managing universal-serial-bus (USB) data transfers. An example system includes a non-transitory computer-readable storage medium including a first scheduling queue for sorting endpoints and a host controller. The host controller is configured to: store a plurality of endpoints for data transfers to the storage medium, an endpoint corresponding to a portion of a USB device; sort the plurality of endpoints in a first order; generate a first transmission data unit including multiple original data packets, the original data packets being allocated to the plurality of endpoints based at least in part on the first order; and transfer the first transmission data unit.

1. A system for managing universal-serial-bus (USB) data transfers, the system comprising:
a non-transitory computer-readable storage medium including a first scheduling queue for sorting endpoints; and a host controller configured to:
store a plurality of endpoints for data transfers to the storage medium, an endpoint corresponding to a portion of a USB device, wherein each endpoint is associated with an endpoint frequency;sort the plurality of endpoints in the first scheduling queue in a descending order based at least partially on endpoint frequency, such that a first endpoint associated with a highest frequency among the plurality of endpoints is stored at a top of the first scheduling queue;generate a first transmission data unit that includes multiple data packets that are allocated to the plurality of endpoints based at least in part on the descending order; andtransfer the first transmission data unit.
