By: iWave systems technology SATA which stands for Serial Advanced Technology Attachment is the serial interface between the Host and SATA drives such as Hard Disk Drives (HDDs) and Solid State Drives (SSDs). SATA is an evolution of the parallel ATA interface that was developed for use as an interconnect for desktop PCs, servers and enterprise systems to connect a host system to peripheral ATA storage devices. The iW-SATA host controller IP is compatible with Serial ATA Revision 2.6 & Advanced Host Controller Interface 1.3.1 and supports features like Native command Queuing (NCQ), auto speed negotiation, all Non-Packet mode commands with extended LBA support. The IP is exhaustively tested at standard data rates of 1.5 Gbps (Gen 1) and 3.0 Gbps (Gen 2) with multiple Hard Disk Drives and Solid State Devices using Linux OS. From the layered architecture, we see that the IP consist of AHCI controller which provides a simple interface for Host bus adapters. DMA engine implemented improves the performance and communicates with transport layer where different protocols are implemented to support the full command set. The FIS generated in Transport layer will be then passed to Link layer which takes care of flow control, CRC calculation and scrambling/descrambling of data. The Physical layer comprises of transceiver available in the industry standard FPGAs.

The target applications also include Consumer Electronics and Portable devices like Tablets, PDAs and Digital communication and RAID controllers.
