Problems solved by technology

[0004] For the current method of detecting the physical layer link, when the physical layer link fails and the application layer controls the lower layer function reset, the entire protocol needs to be restarted, and the physical layer link takes a long time to recover to the connected state. This process It is easy to cause data loss, resulting in low reliability of data transmission

Abstract

The invention provides a physical layer link state detecting method and device. The method comprises the steps of: detecting whether a SATA controller has established a physical layer link; after theSATA controller has established the physical layer link, detecting at least one flag bit of a high-speed serial transceiver included in the SATA controller; determining, according to the result of detecting the at least one flag bit, whether the physical layer link fails; if so, controlling the high-speed serial transceiver by a control module included in the SATA controller to send a link re-establishment instruction to re-establish the physical layer link; and if not, detecting at least one flag bit of the high-speed serial transceiver included in the SATA controller. The method and the device can improve the reliability of data transmission.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for detecting a physical layer link state. Background technique [0002] With the continuous development of electronic information technology, the amount of data that needs to be processed in the process of signal processing and data transmission is increasing. In order to meet the high-speed and stable requirements of users for data transmission and data storage, SATA (Serial Advanced Technology Attachment, serial Advanced Technology Attachment) controller realizes high-speed data transmission. The SATA controller is divided into application layer, transport layer, link layer and physical layer from top to bottom. The physical layer of the SATA controller includes a control module and a high-speed serial transceiver. The control module and the high-speed serial transceiver are responsible for establishing the host-side The physical layer link for data...
