High-Speed Serial Bus Parameter Configuration via Signal Analysis

Solution Overview

Problem

The existing methods for configuring high-speed serial bus parameters are inefficient, particularly as transmission capacity increases, requiring a large number of parameters to be configured, and optimal parameters selected in normal temperature environments may not be available in high/low temperature environments, leading to low efficiency.

Innovation Solution

A method that sends an application signal from the transmit end to the receive end of a high-speed serial bus to acquire signal loss and material type, then searches a parameter configuration table for matching parameters, allowing for quick configuration of the bus based on frequency, loss, and material type, using pre-defined correspondences between these factors.

Solution Approach 1:

The patent pre-configures parameter configuration tables for different temperature environments (high temperature, normal temperature, low temperature) before actual operation. When the device operates, it detects the current temperature environment and directly retrieves the corresponding pre-configured parameters, avoiding the need to search and adjust parameters in real-time during temperature variations.

Solution Approach 2:

The patent changes the parameters based on temperature environment by maintaining multiple parameter configuration tables with different parameter sets optimized for different temperature conditions. The system selects and applies the appropriate parameter set according to the detected temperature environment, ensuring optimal performance across varying thermal conditions.
