The author brings forward a scheme of vxi bus based broadband digitalize monitoring receiver , on the basis of his deep research on vxi bus technology and visual instrument software architecture 本文作者在深入研究vxi總線技術和虛擬儀器軟件體系的基礎上,提出了vxi總線平臺的寬帶數(shù)字化監(jiān)測接收機方案。
A series of new technologies such as software radio , vxibus , dsp , virtual instrument , measurement and instrument , interface technology apply to the broadband monitoring receiver related to this paper . its research not only satisfies the needs of our radio monitoring branch , national defence branch but also breaks the technology blockage 本文涉及的寬帶監(jiān)測接收機將軟件無線電技術、 vxi總線技術、 dsp技術、智能儀器技術、測控技術、接口技術等一系列正在蓬勃發(fā)展的新技術緊密結(jié)合起來,它的研究不僅可以滿足我國無線電監(jiān)測、國防、安全等部門的實際需要,還可以打破少數(shù)發(fā)達國家對我國的技術封鎖,為我國的無線電監(jiān)測、國防、安全等部門的設備建設做出貢獻。
In recent years , radio technology has developed very quickly in our country . however , a radio monitoring receiver with broad frequency scale ( 20 - 3000 mhz ) , high scanning rate ( above 1ghz / s ) and whole spectrum real - time display has not developed . some imported monitoring receivers with broad frequency scale can only scan slowly and could n ' t meet actual needs . not only these imported receivers " price is high but also those developed countries usually limit the quantities of imported receivers and related technology is not open 近年來我國無線電技術水平已經(jīng)有了很大發(fā)展和進步,但對于頻率覆蓋范圍寬( 20 - 3000mhz ) 、掃描速度快( 1ghz / s以上)并具備快速全頻段實時頻譜顯示和記錄的無線電監(jiān)測接收設備,目前我國尚不能生產(chǎn),國內(nèi)現(xiàn)在已經(jīng)進口的寬頻段監(jiān)測接收機一般也只能進行低速掃描,無法滿足實際的需要。
This thesis deals with design and application of a multiprocessor made of four dsps in monitoring receiver . the broadband monitoring receiver requires a kind of chip with high performance because of complicated intermediate frequency signal processing . the author selects a kind of digital signal processor called adsp21160 . during the process of design , the author uses cpld , fpga and some special cpus to finish signal , processing in the monitoring receiver . cluster multiprocessor based on vxibus made of four adsp21160 is put forward . the task distribution of four dsps is solved too . furthermore , data transition methods between chips at a high speed through link ports and chip extension mode using external port are recommended . the author debugs , emulates the program in one adsp - 21160 ez - kit lite and simulates the multiprocessor program in visualdsp + + 本文主要探討了監(jiān)測接收機中多dsp處理模塊的設計與應用,寬帶監(jiān)測接收機的中頻處理數(shù)據(jù)量大、實時性高,這樣,對dsp芯片提出了很高的要求,作者通過比較選擇了最適用于監(jiān)測接收機的數(shù)字信號處理器adsp21160 ,并結(jié)合使用了cpld 、 fpga以及一些專用的cpu來完成監(jiān)測接收機中的數(shù)據(jù)處理。作者提出了由四片adsp21160組成的簇式多dsp處理模塊的結(jié)構(gòu)并配以了vxi總線,論述了簇式結(jié)構(gòu)的特點,解決了多dsp處理模塊中四片adsp21160的任務分配問題。
