[Abstract]:With the rapid development of modern information industry, in various military, civil and industrial fields, it is necessary to record or temporarily store the data processed in different situations, which provides conditions for further observation and analysis. With the continuous development of application field, with the increasing of data volume and data rate, new requirements for storage system are put forward, such as portable, offline, long time, high efficiency storage with large capacity, etc. These strict conditions also promote the continuous development of storage technology. According to the existing requirements, this paper takes the data storage system as the research object, discusses the development prospect and research status of the storage technology, and analyzes the principle of the SATA protocol theory system in detail. A hardware access control scheme based on FPGA is designed. By writing the state machine logic of SATA protocol, the hardware circuit test platform with the interface between FPGA and SATA is built, and the software and hardware are debugged. Finally, the feasibility of the storage scheme is verified. The main work of this paper is as follows: 1. The principle of data transmission in SATA protocol is expounded in detail, and the process of data transmission in each protocol layer and the basis of inheriting PATA protocol are analyzed from the aspects of realization condition, data structure, coding method and so on. 2. The data flow control scheme based on FPGA is adopted, and the function and realization principle of each sub-module are introduced in detail. 3. The state machine logic in FPGA is designed and implemented, and the working process of each sub-protocol layer is described by state transition diagram and text. 4. The design and manufacture of printed circuit board are completed, the basis of layout and wiring in the design is expounded in detail, and the system debugging is carried out in the later stage.
