In order to realize CSRe magnet power-supply control synchronization, our should adopt 32 bit ARM kernel chip and DSP control mode to stable reliable realize control data stream transmission and synchronized instance receiving and dispatching. 为实现CSRe试验环磁铁电源的控制同步,采用32位ARM内核芯片技术结合DSP控制板方式,稳定可靠地实现控制数据流的传输和同步事例的收发。
The article mainly studies the bit stream formats of H.323 terminal on IP network and H.321 terminal on B-ISDN. Through gateway, two terminals implement data stream conversion between different transmission format. 主要研究了H.323终端在IP网络中的媒体流格式和H.321终端在B-ISDN中的媒体流格式,并编程来实现两终端在网关中的数据流转换。
