AI Technical Summary

Technical Problem

Data communication between different devices is hampered by incompatible interface protocols, which can lead to data read/write operations failing or reduced communication efficiency. This is especially true when PC devices use UFS devices, as UFS storage devices cannot be used efficiently on platforms with PCIe interfaces.

Method used

Design a storage device comprising a carrier, a conversion chip, and a storage module. The conversion chip enables protocol conversion between PCIe and UFS interfaces. By utilizing the PCIe interface layer, UFS interface layer, and protocol conversion layer of the conversion chip, data protocol conversion and transmission are achieved, ensuring efficient communication between the electronic device and the storage module.

Benefits of technology

It achieves efficient data conversion between PCIe and UFS interfaces, improves the communication rate between the host and peripheral storage, and enhances the scalability of the device. It enables platforms with only PCIe interfaces to successfully connect to UFS storage devices, and solves the problem of limited data read/write and communication efficiency caused by incompatible interface communication protocols.
