摘　　要：在主机与目标机间建立与通信端口无关的命令驱动式数据通信协议,给出数据包格式及命令功能定义。该协议采用分层和模块化设计方法,支持1553B和RS-232 2种通信端口,通过扩展底层通信管理模块可实现对CAN、SPI、SPACEWIRE等总线的支持。SPARC V8存储器加载和下载软件的运行结果验证该协议的正确性,表明其能屏蔽不同通信端口之间的差异性,实现正常的数据传输。This paper sets up a command-driven data communication protocol between the independent communication ports of the host and target machine and gives its data package format and as well as command function definition.The protocol uses layering and modeling,it achieves two communication interface between 1553B and RS-232,and CAN,SPI,SPACEWIRE other bus support can easily be achieved by the expansion of underlying communication management module.Operation results of SPARC V8 memory load and download software verify the correctness of the protocol,and shows that it can shield differences between the different communication port to realize the normal data transmission.
