片選信號自動生成 - In the design of this project , the author has participated in the following works : the system design , chips selected , and making schematic circuit diagram of the interface hardware , and pcb design 、 debug , and the fpga control - program design , system testing and debugging , and some drivers of wince . this paper will introduce the principle of the dvb - t series standards firstly , then the sketchy design of the system will be stated
本人主要從事系統(tǒng)設(shè)計，接收板硬件原理圖及印制電路板（ pcb ）設(shè)計制作并調(diào)試， fpga控制程序設(shè)計， wince部分驅(qū)動程序開發(fā)和系統(tǒng)聯(lián)調(diào)等工作。本文在介紹數(shù)字地面電視廣播（ dvb - t ）相關(guān)標準的基礎(chǔ)上，闡述了系統(tǒng)總體設(shè)計，軟硬件實現(xiàn)具體方案與原理 - It has been playing an important role in equipping all kinds of arms and services for campaigns , tactical exercises and emergent actions etc . based on the detailed analysis of the exchange ' s architecture and implementing , this thesis points out some disadvantages of the device , such as too many absolute components , not very high enough reliability and security , very large size and weight , operating and maintaining difficultly . considering low power requirement and man - machine interface optimizing design at the same time , the thesis come up with an integrated design scheme to the previous device based on " mcu + cpld / fpga architecture " : ( 1 ) signal frequency dividing , timing frequency producing , 20 customers " led states controlling are implemented in cpld ; ( 2 ) decoding , latching data and controlling signals are implemented in cpld by bus interface between mcu and cpld ; ( 3 ) chip selecting principles and mcu idle mode design are completed under the consideration of low power requirement ; ( 4 ) operation by chinese lcd menus is adopted in the man - machine interface
本項目以該交換機為研究對象，在詳細分析原設(shè)備的系統(tǒng)結(jié)構(gòu)和功能實現(xiàn)方式的基礎(chǔ)上，指出該機型在使用過程中存在技術(shù)相對陳舊、分立元件過多、可靠性和保密性不夠、體積大、重量大、維修困難等問題，同時結(jié)合系統(tǒng)的低功耗需求和優(yōu)化人機接口設(shè)計，本文提出基于“單片機+ cpld fpga體系結(jié)構(gòu)”的集成化設(shè)計方案：在cpld中實現(xiàn)信號音分頻和計時頻率生成電路、 20路用戶led狀態(tài)控制電路； cpld與單片機以總線接口方式實現(xiàn)譯碼、數(shù)據(jù)和控制信號鎖存功能的vhdl設(shè)計；基于低功耗設(shè)計的器件選型方案和單片機待機模式設(shè)計；人機接口的lcd菜單操作方式。
