USB Peripheral Data Transmission Priority Queuing

The patent segments the single data transfer queue into multiple queues (first queue for normal priority data, second queue for high priority data). This segmentation allows high-priority data to be processed separately and transmitted immediately without waiting for aggregation of normal priority data, thus reducing data delay time while maintaining reasonable processor utilization through selective transmission.

The patent applies different quality characteristics to different parts of the data transmission system by implementing priority-based queue management. High-priority data in the second queue receives preferential treatment with immediate transmission capability, while normal priority data in the first queue follows standard aggregation protocols. This local differentiation resolves the contradiction by allowing time-critical data to bypass aggregation delays.

The patent implements dynamic queue management where the system can adaptively switch between aggregation mode and immediate transmission mode based on data priority. The second queue for high-priority data enables dynamic bypass of the aggregation process when needed, allowing the system to optimize between transfer reduction and processor utilization in real-time based on incoming data characteristics.

The patent performs preliminary classification of incoming data into priority categories before entering the transmission queue. High-priority data is pre-identified and routed to the second queue, which is configured for immediate transmission. This preliminary action prevents high-priority data from being subjected to aggregation delays, reducing the need for processor-intensive re-prioritization during transmission.

The patent segments the single processing sequence into multiple priority-based sequences (first queue for normal priority, second queue for high priority). This segmentation allows the system to maintain processing order within each priority level while enabling high-priority data to be processed separately and transmitted immediately, thus reducing delay without completely disrupting order stability.

The patent introduces priority queues as intermediary structures between data reception and transmission. These queues act as mediators that buffer and reorganize data based on priority, allowing high-priority data to be extracted and transmitted immediately while normal priority data continues to follow the standard ordered processing path. This intermediary mechanism resolves the contradiction between maintaining order and reducing delay.
