Abstract: A system includes a cache and a cache-management component. The cache includes a plurality of cache lines that correspond to a plurality of device endpoints. The cache-management component is configured to receive a transfer request block (TRB) for data transfer involving a device endpoint. In response to a determination that the cache both (i) does not include a cache line assigned to the device endpoint and (ii) does not include an empty cache line, the cache-management component assigns, to the device endpoint, a last cache line that includes a most recently received TRB in the cache, and stores the received TRB to the last cache line.

Abstract: 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.

Abstract: Systems and methods are provided for cache management. An example system includes a cache and a cache-management component. The cache includes a plurality of cache lines corresponding to a plurality of device endpoints, a device endpoint including a portion of a universal-serial-bus (USB) device. The cache-management component is configured to receive first transfer request blocks (TRBs) for data transfer involving a first device endpoint and determine whether a cache line in the cache is assigned to the first device endpoint. The cache-management component is further configured to, in response to no cache line in the cache being assigned to the first device endpoint, determine whether the cache includes an empty cache line that contains no valid TRBs, and in response to the cache including an empty cache line, assign the empty cache line to the first device endpoint and store the first TRBs to the empty cache line.
