Abstract: This paper introduces the realization of share memory technology based on CPCI bus, gives an instance of share memory based on Intel 21555 non-transparent PCI-to-PCI bridge, describes the theory of CPCI bus share memory technology, the software setting, and realizes the accessing to share memory space between two processor modules.

Key words: Share memory, Address translation, Memory space

摘要：

研究了基于CPCI总线的共享内存技术的实现，并以Intel 21555非透明PCI-to-PCI桥为例介绍了CPCI总线共享内存技术的工作原理，软件设置，实现了两块处理器模块对共享内存空间的互访。
