针对目前1553B总线已渐渐达不到先进飞机对信息传输速度的要求，设计了高速1553B总线控制器通信管理系统，详细规划了总线控制器与主机间共享存储区的各个模块，运用双缓冲机制降低了消息传输延迟，通过对共享存储区的高效管理，缩短了总线传输多帧数据时的数据等待时间，加快了总线信息的传输速度，有效提高总线利用率。在配置有EXC-1553PCI/MCH板卡的工控机上验证得知，所设计的系统能够可靠地提高总线吞吐率，满足1553B总线向高速率发展的要求。

A communication management system for the high-speed 1553B bus controller was designed because the avai-lable 1553B bus can not reach the requirement of the information transfer rate of advanced planes. Detailed Planning for each module in the shared memory region between bus controller and main engine was made. The information transmission delay is re-duced by using the double buffering mechanism. By the high-efficiency management to shared memery region,the waiting time when the bus transmits multi-frame data is shortened and the transmission speed of bus information is quickened. The bus utiliza-tion ratio was effectively raised. By the validation in the industrial personal computer with EXC-1553PCI / MCH board card,the throughput rate of the designed bus can be raised reliably. The system can satisfy the development requirement of high-speed 1553B bus.
