Serial ATA Host Controller (1.5, 3.0, 6.0 Gb/s)

Overview

The Serial ATA Host IP Core provides an interface to high-speed serial link replacements for the parallel ATA attachment of mass storage devices. The serial link employed is a high-speed differential layer that utilizes Gigabit technology and 8b/10b encoding.
