SCI数据通信技术的研究和实现

Research and Implementation on SCI Data Transmission

随着计算机应用领域的拓展与加深,对计算机性能的要求也越来越高,进而对系统中的信息交互提出了更高的要求。传统的总线技术由于存在固有的限制,已经成为阻碍系统性能提高的瓶颈。SCI的出现克服了总线技术的不足,大大改善了信息交互的效率和带宽,满足了系统中和系统间的互连要求,成为先进互连技术的代表。详细分析了在WindowsXP环境下,开发SCI数据通信程序的原理和方法。

With the development of computer technology, the requirement for the performance of computer and transmission become more and more high. Because of the limitation of traditional bus technology, it becomes the choke point of advance the performance of system. SCI overcomes the limitation, enhances the efficiency and bandwidth of transmission. It meets the demand of current transmission, becomes the mainstream of transmission technology. The architecture of SCI device driver in Windows XP environment is described in this paper and data transmission methods on SCI network are also presented with examples.
