一种高可靠的CPCI背板通信系统防冲突机制的设计与实现

Design and Implementation of a Highly Reliable Anti-Collision Mechanism for CPCI Backboard Communication System

提出一种高可靠主控板和从板数据交互的防冲突机制,在FPGA上实现了相关功能模块,结合CPCI(Compact Peripheral Component Interconnect)背板通信和DPRAM技术,配合CPU软件,保证了主控板和从板之间数据无冲突地传输,大大提高了系统通信的正确性和可靠性。

A highly reliable and anti-collision mechanism for data communication between master and slave control modules was proposed, and corresponding functional modules on the FPGA were realized, which integrated the CPCI backboard communication and DPRAM technologies as well as cooperated with CPU software, so as to implement the anti-collision data transmission between master and slave control modules. This mechanism could promote the accuracy and reliability of the system communication effectively.
