虚拟现实硬件平台上的多机通讯

The Communications in the Several Computers Used in Common Vitual-reality Hard Ware Platform

该文讨论了自行研制的通用虚拟现实硬件平台中的多台计算机间的通讯问题 ,包括 :手形计算机、手位及头位计算机和主控计算机间的通讯 ;主控计算机和SGI图形工作站间的通讯。前者采用自己设计的多机并行通讯卡在DOS下完成 ,后者在UNIX和DOS间通讯 ,采用以太网和TCP/IP协议的UDP方式完成。

The article discusses the communications in the several computers used in common vitual-reality hard ware platform. It includes:communications in palm computer,hand located computer,head located computer,and main computer;the communications between main computer an sgi pictures workstation.The former adapts mupli-computer LP communication card,the later communicates between unix and DOS,which adapt ENTER network and UDP of TCP/IP.The multi-computer communication of virtual-reality hare ware platorm.
