[0074] There are two core design ideas followed in the design of the present invention:
[0075] (1) Provide users with as simple an application interface as possible, so that users can feel that reading and writing disks is as easy as reading and writing SRAM chips.
[0076] (2) The SATA protocol is realized with a clear structure, and in order to achieve the purpose of simplifying the user interface, the design is encapsulated in a higher level in addition to the SATA protocol. That is, in addition to the physical layer, link layer, and transport layer described in the SATA protocol specification, a layer of logic is also encapsulated and named as the application layer.
[0077] The invention uses the Virtex5 series FPGA device (specific model XC5VLX110T-1FFG1136C) of Xilinx Company in the United States as a development platform. Among them, the SATA physical layer logic is implemented based on the high-speed serial data transceiver named GTP integrated inside the FPGA chip; the l...
