According to the traditional PCs defect that the PCI bus forms the bottleneck of system communication, we propose the design of Parallel PC architecture for switching network centric.
针对传统的PCI总线结构形成系统通信瓶颈的缺陷，提出了以交换网络为中心的可扩展并行PC体系结构设计思想。
This bridge is the core of communication of the controller system, it connects the bottom level backplane bus, backplane bus controller, and PC EPP parallel port.
该总线桥是某型协调控制器系统的通讯核心，实现了系统下层的背板总线、背板总线管理器与上位机epp并口之间的协议转换以及通讯仲裁功能。
Due to lack of data and address parallel bus on TMS320F2808, the two DSPexchange data by means of communication through SPI interface.
由于采用的TMS320F 2808不具备数据总线与地址总线，两个DSP之间采用SPI串行通讯的方式实现数据交换。
