Title:
EQUALIZATION TRAINING METHOD, APPARATUS, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/244065
Kind Code:
A1
Abstract:
An equalization training method, apparatus, and system. The method comprises: acquiring the training speed of a target phase of a main chip and a slave chip during equalization training (900); determining a target speed threshold interval in which the training speed of the target phase is located, and according to the correspondence between N+1 speed threshold intervals and N+1 equalization time-out times, determining a target equalization time-out time corresponding to the target speed threshold interval, and configuring the target equalization time-out time as the equalization time-out time of the target phase; then the main chip and the slave chip performing equalization training on the target phase within the equalization time-out time of the target phase. The described method can flexibly configure an equalization time-out time used for equalization training for each equalization training process, thus enabling the configured equalization time-out time to better comply with the current training speed used for link negotiation, better ensure that equalization parameters are found within the configured equalization time-out time, and increase the success rate of equalization training.
