| 13 | The Ceva SATA controller mostly conforms to the AHCI interface with some | |
| 14 | special extensions to add functionality, is a high-performance dual-port | |
| 15 | SATA host controller with an AHCI compliant command layer which supports | |
| 16 | advanced features such as native command queuing and frame information | |
| 17 | structure (FIS) based switching for systems employing port multipliers. | |
