摘　　要：针对可编程片上系统(SOPC)的光纤通道适配器设计,分析了XPS Central DMA和Scatter-Gather DMA两种DMA的特点.并在开发板上做了硬件实现,实验结果表明Scatter-GatherDMA传输速率可以达到225MB/s,满足光纤通道传输速率要求(200MB/s).In order to design a Fibre Channel based on Programmable System on Chip （SOPC）, both the XPS Central DMA and the Scatter-Gather DMA are studied. Finally some tests are done on a development board, and the experimental results show that the Scatter-Gather DMA data transmission rate can reach 225MB/s, which meets the Fibre Channel transmission rate requirements （200MB/s）.
