PCI bridge-based dual CPUs communication technology
基于PCI桥的双CPU通信技术

Most of the PCI bus cards are implemented based on PCI bus bridge and special micro-processor chip to fulfill specific requirements. For advanced application with PCI bus cards, embedded CPU and OS are used. Environment characteristics of dual CPUs on PCI bridge were researched, and key points about communication design were summarized. The configuration and usage of typical PCI bridge were studied, and an example of security network interface card based on our research was introduced.
