SATA Interface Technology Research And Design

SATA (Serial ATA) is the latest generation of desktop computer hard disk storage interface technology, with high transfer rates, hot-swappable and strong error correction capacities etc, which has been widely popular in the industry and the mainstream of the computer's hard drive by gradually replacing the parallel interface. The problems existing in the parallel ATA hard drive array that the wide ribbon cable's effective distance is short and the disadvantages of the structural connection and cable distribution have been solved well by the exploitation of SATA.In this thesis, related technologies of SATA interface are discussed at first. Basic conceptions, production and development processes, technical performance and characteristics of SATA are introduced. The key technology of the SATA- Serial communication clock recovery technique is deeply studied.Secondly, this thesis has made a detailed analysis of the SATA protocol and its four sub-layers. The roles, functions, modes, processes, signal formats and transmission of information of all levels are discussed.At last, ALTERA company 40 nm FPGA solution for SATA storage and high-speed FPGA transceiver of Arria II GX serial are used integrated with SATA protocol to implement the conversion between the serial and parallel data and the high speed data transfer. The data storage controller based on the SATA interface is designed and the relevant simulation and post-certification are completed. The realization of the reset process on the physical layer, CRC module and the state machine conversion process on the link layer, scrambling module are analyzed and illuminated. The controller designed in this thesis can achieve the basic functions of SATA protocol, and the data can be read and written freely.
