The Integrated Design Of A SPC Exchange System

The wired correspondence method is high because of having a confidentiality, the anti- interference's ability be strong to doubly be subjected to favor in the military the correspondence, therefore, wired to for use by the military correspondence equipments of research and design have very important strategic meaning. With develop a quickly public SPC Exchange technique to compare, currently in the troops use of small scaled exchange machine expose a technique opposite and old, cent sign a component excessive, credibility and confidentiality be not enough, physical volume big, weight big, maintain difficulty etc. problems. Through analysis structure and design module pieces of the small scaled field SPC Exchange System, according to the integration design way of the "CPU+CPLD/FPGA" system structure, and combining the principles of low achievement consume demand and optimized the way of the man-machine conversation, this thesis mainly research and realize the CPLD integration design, the low achievement consume design, the man-machine conversation of LCD menu's operation's way's etc. work. The main work of this thesis carry on have:(1) Analyzing at present technique and application present condition of the main wired equipments-field Exchange System in army's troops. Aimed at the research level of the small scaled SPC Exchange System and current realistic need to it in troops, put forward a research topic.(2) According to the general distance of SPC Exchange System, design the function frame of the system diagram, puts forward the design way according to the "CPU+CPLD/FPGA" system structure, explicit study point.(3) Carried on a first step design to the main function mold piece of system and carried on function design and hardware to edit and translate to the CPLD. Combining with writing of the whole machine software and adjust to try, the each function mold piece carried on a test.
