摘　　要：分析了目前市面上常见的数字显微镜设计方案的利弊,提出在嵌入式平台上设计数字显微镜具有成本和性能优势。详细阐述了利用XPLD芯片配合大容量的DDR SDRAM实现数字显微镜的方案。具体分析了设计中通过定制DDR控制器解决大容量存储器和建立随机存储缓冲区的方法。Based on comparison and analysis of the mostly used methods on digital microscope, this paper points out that the embedded platform is more favorable for digital microscope because of lower cost and better performance. With the use of XPLD and DDR SDRAM, we post a cost effective and high performance solution. And a detailed description is given for the two key points in the solution： integrated large size memory and high speed buffer with DDR controller.

关 键 词：XPLD DDR控制器 高速图像采集
