【摘要】：随着社会的发展和信息量的增加，，人们对信息存储系统速度和容量的需求不断提升，对数据传输的速度和可靠性也提出了更高的要求。传统的并行传输方式由于存在时钟和数据间偏移，PCB布线难度大，信号间串扰严重等问题，已很难满足高速系统的要求。而高速串行传输技术凭借其带宽大、抗干扰性强和接口简单等优势，正迅速取代传统的并行技术，成为业界的主流。尤其是串行传输技术与现场可编程门阵列（FPGA）技术的结合，使得串行接口的设计变得更为简单和灵活。 本文利用Xilinx公司Virtex-4系列FPGA中的串行接口模块RocketIO MGT为主要数据传输手段，设计了一个高速视频流存储系统。该系统以Virtex-4系列FPGAXC4VFX100、ADSP BF537和NAND Flash K9NCG08U5M为核心器件，能够对并行LVDS接口、Fibre Channel4X光纤接口和Camera Link高速相机接口输入的高速数据进行实时的存储，并能通过另一个Fibre Channel4X光纤接口对存储数据进行高速的下载，该系统同时还具有检测坏块的功能和规避坏块的设计。此外，本文还对系统的关键部分进行了必要的仿真，以验证设计的可行性。
[Abstract]:With the development of the society and the increase of the amount of information, the demand for the speed and capacity of the information storage system is increasing, and the speed and reliability of the data transmission are also required. Because of the clock and data offset, the difficulty of PCB routing and the serious crosstalk between signals, the traditional parallel transmission mode is difficult to meet the requirements of high-speed systems. The high-speed serial transmission technology, with its advantages of large bandwidth, strong anti-jamming and simple interface, is rapidly replacing the traditional parallel technology and becoming the mainstream of the industry. Especially the combination of serial transmission technology and field programmable gate array (FPGA) technology makes the design of serial interface more simple and flexible. In this paper, a high speed video stream storage system is designed by using the serial interface module RocketIO MGT in Virtex-4 series FPGA of Xilinx Company as the main means of data transmission. With Virtex-4 series FPGAXC4VFX100,ADSP BF537 and NAND Flash K9NCG08U5M as the core devices, the system can store the high speed data input from parallel LVDS interface, Fibre Channel4X fiber interface and Camera Link high speed camera interface in real time. It can download the stored data at high speed through another Fibre Channel4X fiber interface. The system also has the function of detecting bad blocks and avoiding the design of bad blocks. In addition, the key parts of the system are simulated to verify the feasibility of the design.
