SATA-IP Host reference design on 7-Series and KCU10
■Serial ATA (SATA) is an evolutionary replacement for the Parallel ATA (PATA) physical storage interface. SATA interface increases speed transfer to be 3.0 Gbps for SATA-II, and 6.0 Gbps for SATA-III. To communication by SATA protocol, there are four layers in its architecture, i.e. Application, Transport, Link, and Phy.
■The Application layer is responsible for overall ATA command execution, including controlling Command Block Register accessed. The Transport layer is responsible for placing control information and data to be transferred between the host and device in a packet/frame, known as a Frame Information Structure (FIS). The Link layer is responsible for taking data from the constructed frames, encoding or decoding each byte using 8b/10b, and inserting control characters such that the 10-bit stream of data may be decoded correctly. The Physical layer is responsible for transmitting and receiving the encoded information as a serial data stream on the wire.
■This reference design provides evaluation system which implements all SATA communication layers for Host side to transfer high speed data with SATA-III or SATA-II Device. The SATA-IP core is designed to operate with GTP/GTX/GTH transceiver of 7-Series and Ultrascale device for lower layer protocol and processor for upper layer protocol.
