Receiver Equalization Settings for High-Speed IC Links

The patent applies preliminary action by pre-configuring multiple transmitter preset settings and receiver parameter combinations before communication occurs. The system performs link equalization operations in advance to determine optimal settings, storing these configurations for subsequent use. This allows the system to prepare optimal communication parameters beforehand, resolving the contradiction by enabling high-performance communication without requiring complex real-time adjustments during data transmission.

The patent implements parameter changes by systematically varying transmitter preset values and receiver parameters (such as equalization coefficients, sampling phases, and decision thresholds) to find optimal combinations. The system changes multiple parameters simultaneously across different preset configurations, evaluating each combination's effect on communication performance. This resolves the contradiction by transforming the fixed, simple preset approach into a dynamic parameter optimization process that achieves high performance while maintaining manageable complexity through structured parameter exploration.

The patent applies segmentation by dividing the link equalization process into distinct stages: transmitter preset testing, receiver parameter evaluation, and optimal combination selection. Each stage processes specific subsets of parameters independently, allowing parallel evaluation of multiple configurations. This segmented approach resolves the time-performance contradiction by organizing the exhaustive search process into manageable segments that can be efficiently processed and combined, reducing overall equalization time while maintaining comprehensive performance optimization.

The patent uses preliminary action by pre-evaluating and storing the results of link equalization operations for multiple transmitter preset settings before actual communication begins. The system performs comprehensive parameter optimization in advance, caching the optimal receiver parameter combinations for each transmitter preset. This preliminary preparation resolves the contradiction by shifting the time-consuming optimization process to occur before data transmission, allowing fast retrieval of pre-determined optimal settings during actual communication without sacrificing performance.

The patent implements universality by designing the receiver setting table and control circuit to handle multiple transmitter preset settings through a single unified structure. The receiver setting table stores parameter combinations that are universally applicable across different preset configurations, and the control circuit uses a standardized process to evaluate and select optimal settings regardless of which transmitter preset is active. This multi-functional design resolves the contradiction by enabling comprehensive parameter optimization without requiring separate dedicated structures for each preset, thus improving performance while controlling complexity through shared resources.

The patent applies equipotentiality by creating a standardized evaluation framework where all transmitter preset settings and receiver parameter combinations are assessed using the same criteria and processes. The link equalization operation maintains consistent evaluation conditions across different presets, ensuring that optimal settings are determined through uniform methods rather than ad-hoc adjustments. This equipotential approach resolves the contradiction by providing systematic, consistent optimization that improves communication performance across all presets without requiring complex, preset-specific receiver structures.
