Serial ATA (SATA) is a high-speed serial bus interface used to transfer data from motherboards to peripheral storage devices, such as optical disk drives, HDDs and solid state disk drives. The SATA interface is being integrated into SoCs for consumer electronic products and enterprise class storage systems, such as STBs. It is emerging as the mass storage interface of choice.

Today, it is not unusual to see terabytes of storage in the home to facilitate picture, audio and video media storage. According to IDC, the average home storage per gigabyte is predicted to outpace commercial storage by 2015.

Due to this demand, the SATA interface is increasingly becoming available as third party intellectual property (IP) to help speed development time and lower costs. The quality, completeness and interoperability of this IP become the key considerations to the SoC integrator. This article describes the SATA complete IP solution for both host and device applications.
