用法和例句

For improving network interface card s communications performance,the implementation of virtual-physical address translation is reatized in the user s space through the memory mapped of address manage table,and the communications data s zero copy is realized from the user s space to the network interface card(NIC).

介绍了信令寻径式光纤通道交换网的特点,为了提高光纤通道交换网络接口卡的通信性能,通过地址管理表的内存映射实现在用户空间实现虚实地址转换,实现用户数据从用户空间到网络接口卡(NIC)的零拷贝,因此大大提高了NIC的通信速度,优化了其体系结构;并将其成功应用于中尺度数值天气预报的MM5模式中,为各级气象部门提供准确、高效的数值预报服务;测试结果表明,零拷贝技术能够使网络接口卡性能有较大提高,达到了设计目的。

Free Image-Based Virtual Space (FIBVS) is a kind of virtual space, which supports free walkthrough by organizing real world images or videos captured by cameras.

自由虚拟实景空间(Free Image-Based Virtual Space)是以照相机或摄象机拍摄的实景图象为基本数据，经处理后建立起的能够自由漫游的虚拟实景空间。
