摘　　要：针对IA-64平台地址空间和数据空间的特点,该文给出一种简单有效的地址转换与数据表示方法,在此基础上提出可以有效保持虚拟接口结构(v irtua l in terfacearch itecture,V IA)各层抽象描述与具体实现相一致的设计方案。在自主研制的V IA通信硬件基础上,实现了一个软硬件有机结合的实例THV IA 64。测试结果表明THV IA 64不仅可以稳定运行,而且具有很高的通信性能,8 B延迟为9μs,最大带宽为119 M B/s。对比数据表明V IA在IA-64平台上可以展示出更好的性能。The characteristics of the IA-64 address space and data space were studied to develop a simple and efficient method for address conversion and data expression in a design that keeps the same general description and specific implementation on each virtual interface architecture （VIA） layer. Performance tcsts on an self-made VIA communication system, THVIA64, which makes full use of thc hardware, showes that the system is very stable with 9μs latency for 8 B and 119 MB/s maximum bandwidth. The results indicate that the VIA provides better performance on the IA 64 than on the IA-32.
