摘要
针对多弹头、多目标遥测实时数据处理的要求,设计了一块计算机接口卡。卡上带有4个数据缓冲块,每块设计为乒乓缓冲工作方式.独立地承担一路PCM遥测实时数据的缓冲存储、处理。计算机存取采用存储器分页、地址映射方式。各路实时数据接收码率可达1Mbit/s以上。若相邻通道级联,实时接收码率可成倍地提高,单路接收最高可达4Mbit/s以上,完全可以满足常规兵器PCM遥测实时数据处理的要求。
Based on the requirement of multi-bullet & mul-ti-goal telemeter real-time data acquisihon & procession. aboard of a computer interface was designed. This boardholds four block of data buffers. and each one works in aPing-pang buffer operation rnede. seperately fulfills pro-cessing & storing of one channel PCM telemeter real-timedata. The computer proceases in Paging memory & addressshadow mode. The rate of real-time acquisition for eachone channel is over 1Mbit/s. If caseade each other chan-nel. the rate of acquisition increases folderly. the highestrate of one channel acquisition is over 4Mbit/s. This completely fits the requirement of regular arm PCM telemeterreal-time data acquisition & procession.
