• 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。
• As mainstream chip production technology shifts from one generation to the next every three to five years , plants with new technology can make more powerful chips at lower costs , while plants with outdated equipment , which often cost billions of dollars to build , will be marginalized by the maker
  由于主流芯片生产技术每隔3 5年都要进行更新换代，所以掌握了新技术的厂家就可以以较低的成本制造出较好的芯片，而那些耗费数十亿美元建立起的厂家，如果设备落后，也将会被生产商所淘汰。
