【摘要】：随着信息技术的高速发展，容量大、存取速率高、安全可靠的数据存储器的研制越来越具有现实应用价值。本课题的研究可以解决高速数据存储中的关键技术，为观测载荷提供标准、高效、安全的数据存储。论文以研究星载高速大容量数据存储器中的数据传输和存储可靠性为目的，根据实际需求，研究并改进了存储器中的关键技术。论文首先介绍了课题的研究背景、意义以及关键技术的研究现状。随后分析比较关键技术中每种方案的优点和不足，并根据实际需求，选出并改进了一种能够实现高速总线接口标准和数据存储纠检错技术的方案，最后在Xilinx公司的FPGA上进行实现和验证。同之前的设计相比，论文的创新点主要体现在以下几个方面：参考最新的SATA协议—SATA3.0作为高速总线接口标准；在实现SATA总线接口的物理层中未使用FPGA内部集成的高速串行收发器，而是采用TI公司的TLK2711高速收发器，增加了带宽，同时增强了设计的可移植性；在存储模块，增加更加有效的纠检错技术—RS(255,239)编译码。存储系统的主控模块用单片FPGA实现控制逻辑，每个存储板上也用单片FPGA进行设计。方案采用模块化的设计思想，具有可移植、易扩展的特点，，程序运行稳定、功能基本实现。
[Abstract]:With the rapid development of information technology , large capacity , high access speed , reliable and reliable data storage , the research can solve the key technology in high - speed data storage and provide standard , efficient and secure data storage for observation load . In order to study the data transmission and storage reliability of the high - speed large - capacity data storage , the paper introduces the research background , significance and the research status of the key technology , and then analyzes the advantages and disadvantages of each scheme in the key technology . According to the actual demand , the paper selects and improves a scheme which can realize the high - speed bus interface standard and the data storage and error detection technology , and finally realizes and verifies the FPGA of the company . Compared with the previous design , the innovation point of the thesis is mainly embodied in the following aspects : referring to the latest SATA protocol - SATA3.0 as the high - speed bus interface standard , using the high - speed serial transceiver integrated with the FPGA in the physical layer of the SATA bus interface , but using the TLK2711 high - speed transceiver of TI company , increasing the bandwidth , and enhancing the portability of the design . In the storage module , the more efficient error detection technology - RS ( 255,239 ) coding code is added . The main control module of the storage system realizes the control logic by a single chip FPGA , and is also designed by a single chip FPGA on each storage board . The scheme adopts the modularized design idea , has the characteristics of portability and easy expansion , and the program is stable and the function is basically realized .
