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总线技术和虚拟仪器软件体系的基础上,提出了vxi总线平台的宽带数字化监测接收机方案。
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 本文涉及的宽带监测接收机将软件无线电技术、 vxi总线技术、 dsp技术、智能仪器技术、测控技术、接口技术等一系列正在蓬勃发展的新技术紧密结合起来,它的研究不仅可以满足我国无线电监测、国防、安全等部门的实际需要,还可以打破少数发达国家对我国的技术封锁,为我国的无线电监测、国防、安全等部门的设备建设做出贡献。
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 近年来我国无线电技术水平已经有了很大发展和进步,但对于频率覆盖范围宽( 20 - 3000mhz ) 、扫描速度快( 1ghz / s以上)并具备快速全频段实时频谱显示和记录的无线电监测接收设备,目前我国尚不能生产,国内现在已经进口的宽频段监测接收机一般也只能进行低速扫描,无法满足实际的需要。
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 + + 本文主要探讨了监测接收机中多dsp处理模块的设计与应用,宽带监测接收机的中频处理数据量大、实时性高,这样,对dsp芯片提出了很高的要求,作者通过比较选择了最适用于监测接收机的数字信号处理器adsp21160 ,并结合使用了cpld 、 fpga以及一些专用的cpu来完成监测接收机中的数据处理。作者提出了由四片adsp21160组成的簇式多dsp处理模块的结构并配以了vxi总线,论述了簇式结构的特点,解决了多dsp处理模块中四片adsp21160的任务分配问题。
