Abstract

The invention discloses a method and a system for acquiring a communication interface boundary of a storage module, belonging to the technical field of communication. The method for acquiring a communication interface boundary of a memory module comprises that follow steps: the control unit sends a clock signal to the memory unit with a default clock phase, delays the signal input interface of thecontrol unit, and identifies a communication state of the signal input interface; when the communication state of the signal input interface is normal, the phase of the clock signal is adjusted, thesignal input interface is delayed, and the boundary of the signal input interface is obtained. The invention realizes the purpose of finding the boundary of the communication interface (i.e., the signal input interface) by adjusting the phase of the clock signal sent by the control unit to the storage unit and delaying the signal input interface of the control unit, so as to adjust the signal lineaccording to the boundary of the communication interface and improve the stability of the storage module.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a system for obtaining the boundary of a communication interface of a storage module. Background technique [0002] In the use of SDIO (Secure Digital Input and Output Card, secure digital input and output card) interface, as the frequency increases, the problem of SDIO stability is gradually exposed. Since the highest frequency of SDIO is 200Mhz, a valid data cycle is about 5ns (nanoseconds). However, the adjustment of the SOC chip (System-on-a-Chip) read setting (the traditional way is to set the SDIO read setting based on empirical values) It can rarely cover 5ns, and it is impossible to obtain the window boundary of read data and the characteristics of each signal line, so it is impossible to accurately adjust the signal line to improve the stability of SDIO. Contents of the invention [0003] Aiming at the problem that the boundary of the communication ...
