基于CPCI总线的共享内存技术的实现

Technology of Share Memory Based on CPCI Bus

研究了基于CPCI总线的共享内存技术的实现,并以Intel21555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。

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.
