PCIE clock compatibility method and device for solid state disk, computer equipment and storage medium

Abstract

The invention discloses a PCIE clock compatibility method and device for a solid state disk, computer equipment and a storage medium, and the method comprises the steps: configuring the timeout time of solid state disk firmware; judging whether a PCIE reference clock is detected within a timeout time range or not; if yes, the solid state disk firmware selects a PCIE reference clock as a referenceclock of a solid state disk PCIE link; and if not, the solid state disk firmware selects the local clock as the reference clock of the PCIE link of the solid state disk. According to the invention, the solid state disk can stably obtain the reference clock; compared with the prior art, the method has the advantages that normal operation of the solid-state disk is guaranteed, compatibility of the solid-state disk is improved, for a host which does not provide a PCIE reference clock, a local clock can be selected as a reference clock of a PCIE link of the solid-state disk, and connection time ofthe solid-state disk and the host PCIE link is shortened to the maximum extent.

Description

technical field [0001] The present invention relates to a solid-state hard disk, more specifically a PCIE clock compatible method, device, computer equipment and storage medium for a solid-state hard disk. Background technique [0002] As a PCIE (High Speed ​​Serial Computer Expansion Bus Standard) device, the SSD is connected to the computer motherboard through the PCIE slot. The SSD controller uses the REFCLK+ and REFCLK- signals provided by the motherboard as the reference clock for the PCIE link. The controller uses this set of signals Synchronized with motherboard processor system. [0003] Such as figure 1 As shown, most of the motherboards currently provide the REFCLK signal + and REFCLK- signals for the PCIE slot, and the SSD controller and the PCIE link of the motherboard use this differential signal, so that the PCIE device and the PCIE link of the motherboard can be easily linked. . However, some motherboards with poor compatibility cannot provide REFCLK + and ...

AI Technical Summary

Problems solved by technology

However, some motherboards with poor compatibility cannot provide REFCLK signal + and REFCLK- signal, which directly causes the PCIE module of the SSD controller to fail to work normally.
