异构多处理环境下的通信模块设计

Design of communication modules for secondary core in secure Windows terminal

针对传统Windows终端系统的网络信息安全问题,在异构多处理系统安全架构上,利用双端口存储器实现主辅核通信,通过设计通信的缓冲机制、通信协议及辅核外网通信驱动,完成了系统的通信模块,实现了异构多处理系统安全架构上的高速网络通信。

The network security problem in traditional Windows terminals has become increasingly important. Based upon the dual-core security architecture for both hardware and software, dual-port RAM was used to implement the communication between the primary core and the secondary core. The buffering mechanism, communication protocol as well as the driver for secondary core residing in external networks were discussed. Moreover, the high speed connection between the host and the secondary core, and the secure Windows terminal＇s communication module for secondary core were implemented.
