A computerized system is disclosed. The computerized system may include one or more processors configured to perform the operations stored in a memory. The operations may include sorting a subset of a plurality of endpoints for communication during a communication frame first based on service interval time assigned to each endpoint and then resorting based on a concurrency score of each peripheral device corresponding to the subset of the plurality of endpoints. The operations may include determining available bandwidth and a number of packets to be communicated with the each endpoint of the subset of the plurality of endpoints. The operations may include generating a scheduling table that includes the number of packets and an order of communication of the packets to be communicated with the each endpoint of the subset of the plurality of endpoints.

Method and apparatus for USB periodic scheduling optimization

An improved USB host controller and method supports concurrent host and device debug operations with only one usable USB port. The described embodiments save silicon cost and avoid additional connectors, which are undesirable in ever-smaller devices.
