Dynamic Priority Arbitration for Data Transmission Balance

The patent implements dynamic priority adjustment where the priority of each data source is not fixed but changes over time based on a round-robin scheduling mechanism. The arbitration unit dynamically updates priority sequences in each cycle, ensuring that data sources that have not transmitted recently receive higher priority, thus balancing data transmission across multiple sources while maintaining manageable arbitration complexity through systematic priority rotation.

The patent segments the arbitration process into multiple levels (first-level arbitration units and second-level arbitration units), where each level handles specific aspects of priority determination. The first-level units perform initial arbitration based on round-robin priorities, and the second-level unit performs final arbitration. This segmentation distributes the arbitration complexity across multiple simple units rather than requiring one complex arbitration unit, thus achieving balanced data transmission while keeping individual arbitration units relatively simple.

The patent merges the priority determination function and the arbitration function into an integrated arbitration unit. The arbitration unit simultaneously maintains priority sequences for multiple data sources and performs arbitration based on these priorities in a unified process. This merging reduces system complexity by eliminating separate priority management and arbitration components, while still achieving effective multi-level arbitration through the integrated unit's ability to handle both functions cooperatively.
