Hardware Statistics Management via Register Interface

The patent extracts the statistic update operation from the CPU's read-modify-write sequence and implements it as a single atomic write operation through a dedicated hardware interface. The register interface and update logic are pulled out from general CPU operations, allowing statistic updates to occur without consuming CPU cycles for reading or modifying data, thus resolving the contradiction between reliable tracking and system performance.

The patent introduces a register interface as an intermediary between the CPU and the statistic records in RAM. This intermediary layer handles the atomic update operations, including reading the current value, modifying it, and writing back the updated value, all within a single write operation from the CPU's perspective. This mediator eliminates the need for CPU to perform multiple read-modify-write cycles, resolving the performance degradation issue while maintaining accurate statistic tracking.

The patent merges multiple statistic record updates into a single atomic write operation. The register interface collects multiple data elements corresponding to different statistic records and performs all updates in one operation cycle. This combining approach maintains the precision of individual record updates while dramatically reducing CPU resource usage by eliminating multiple separate read-modify-write cycles.

The patent implements preliminary action by having the register interface prepare and buffer multiple data elements before executing the atomic update operation. The interface holds multiple statistic updates in ready state, then performs them all together in a single operation, preventing the need for multiple separate CPU interventions and reducing overall resource consumption while maintaining accuracy.

The patent creates a universal register interface that can update any statistic record in the array without requiring specialized memory circuits. The same generic interface and update logic handle all statistic updates uniformly, whether for packet counts, byte counts, or other metrics. This multi-functional approach achieves fast update speeds through hardware acceleration while maintaining ease of manufacture and scalability, as the solution doesn't require custom-designed memory arrays for different statistic types.

The patent implements self-service by enabling the register interface to autonomously perform atomic update operations on statistic records without requiring complex customized memory circuits. The interface itself provides the intelligence needed for efficient updates, using simple RAM for storage and handling all the complexity of atomic operations, address generation, and data element processing. This self-sufficient approach eliminates the need for expensive custom memory while maintaining high update speeds.
