Method, Apparatus, and System for Configuring High-Speed Serial Bus Parameter

摘要

A method for configuring a high-speed serial bus parameter, including sending an application signal from a transmit end of a high-speed serial bus to a receive end of the high-speed serial bus, searching a parameter configuration table for a high-speed serial bus parameter that matches all of a frequency of the application signal, a loss of the application signal on the high-speed serial bus, and a material type of a wiring board of the high-speed serial bus, and configuring the high-speed serial bus according to the high-speed serial bus parameter. According to the method, a problem involving configuration of a high-speed serial bus parameter when a transmitted signal is compensated may be solved.

1. A method for configuring a high-speed serial bus parameter, comprising:
sending an application signal from a transmit end of a high-speed serial bus to a receive end of the high-speed serial bus, wherein the application signal is used to carry information about transmission data; acquiring a loss of the application signal on the high-speed serial bus and a material type of a wiring board of the high-speed serial bus; acquiring a frequency of the application signal according to one of a transmit rate and a receive rate of the application signal; searching a parameter configuration table for theft high-speed serial bus parameter that matches all of: the frequency of the application signal, the loss of the application signal on the high-speed serial bus, and the material type of the wiring board of the high-speed serial bus, wherein the parameter configuration table comprises a correspondence between a bus parameter and a signal frequency, a signal loss, and a material type of a wiring board, and configuring the high-speed serial bus according to the high-speed serial bus parameter.
