SATA SPEED AUTO-NEGOTIATION METHOD AND DEVICE BASED ON THIRD-PARTY PHY

摘要

Disclosed are an SATA speed auto-negotiation method and device based on a third-party PHY and a computer storage medium. The method comprises: receiving parallel data recovered by a PHY, and performing byte alignment on the parallel data according to K codes; detecting whether the aligned parallel data contain OOB signals; when the aligned parallel data contain OOB signals, sending the OOB signals to an SATA controller; and after the SATA controller identifies the OOB signals, receiving speed selection signals sent by the SATA controller, and sending the speed selection signals to the PHY.
