Clock Signal Processor Duty Cycle Correction Latency

The patent applies preliminary action by executing duty cycle correction during the latency period, which is a time window already allocated for memory operations. The switch point calculator determines when to activate the duty cycle corrector based on pre-calculated latency duration, allowing correction to occur in advance without impacting normal data transmission timing. This resolves the contradiction by utilizing otherwise wasted latency time for beneficial correction activity.

The patent implements periodic action by activating the duty cycle corrector at specific periodic intervals - namely at the end of each latency period. The switch point calculator monitors the clock signal and triggers correction only during these predetermined latency windows, rather than continuously. This periodic activation maintains data transmission accuracy while minimizing time overhead by limiting correction operations to necessary latency periods.

The patent applies feedback through the switch point calculator, which continuously monitors the clock signal and latency period duration to determine the precise moment for activation. The calculator uses feedback from the clock signal edges and latency timing to accurately trigger the duty cycle corrector at the optimal moment. This feedback mechanism ensures that even though correction occurs during latency (reducing time overhead), the timing precision is maintained through continuous monitoring and adaptive activation timing.

The system performs self-service by using the latency period itself as the timing reference for activation. The switch point calculator leverages the existing latency duration (which is already a built-in timing parameter of the memory operation) to determine when to start correction, rather than requiring external timing signals. This self-service approach reduces the need for additional precise timing infrastructure while maintaining adequate timing precision for effective duty cycle correction.

The patent applies segmentation by dividing the duty cycle correction function into distinct modular components: the edge detector for detecting clock edges, the phase interpolator for calculating duty cycle adjustments, and the switch point calculator for timing control. Each module performs a specific function and can be independently optimized or implemented. This segmentation achieves high duty cycle accuracy through coordinated operation of specialized modules while managing device complexity through functional decomposition rather than a monolithic complex system.

The patent implements local quality by applying duty cycle correction selectively only during the latency period rather than continuously. The switch point calculator enables the duty cycle corrector to operate with high precision locally during the latency window when it is most needed, while remaining inactive or bypassed during normal operation periods. This localized application of correction maintains high duty cycle accuracy when required without unnecessarily increasing overall device complexity through continuous operation infrastructure.
