为满足高速全景图像的实时无损存储的需求，设计了基于现场可编程门阵列（ field-programmable gate array ，FP-GA）的SATA阵列和TF卡阵列嵌入式存储系统。用2片FPGA作为控制器，分别负责全景图像的采集处理任务与存储传输任务，设计了8层PCB板级硬件系统并对高速数字信号线进行了细致的阻抗匹配，并设计了支持SD3．0协议的RTL级控制器。实际测试TF卡阵列存储平均速度为227．36 MB／s，峰值速度达293 MB／s，实现了数据的高速存储功能。

In order to satisfy the need for the real-time and loss-less storage of a high-speed panoramic image , an embedded image data storage system based on FPGA with SATA array as well as TF card array is designed .The controller consists of two pieces of FPGAs , which and they are in charge of collecting/processing and storing/trans-fer missions of the panoramic image respectively .Further, a hardware system with a PCB board of eight layers is devised, and an impedance match is performed for the high-speed digital signal lines .Then, an RTL-level control-ler that supportes SD3.0 protocol is projected.Finally, the actual test shows that the average speed of TF cards ar-ray is 227.36 MB/s and the peak speed is up to 293 MB/s, thus a high-speed storage capacity of the data is a-chieved by the developed system .
