The M-PHY® specification is designed to allow mobile devices to have a low-power, high-performance interface. Several higher level protocols use the M-PHY physical layer for storage, I/O and memory in mobile devices.

This presentation discusses how higher layer protocols, including UniPro® and UFS, use the M-PHY physical layer to provide an efficient, low power storage protocol to be enabled on mobile platforms. It also covers debug and analysis techniques for UFS and UniPro technologies to allow root-cause analysis to be performed in an efficient and effective manner.
