expander board 中文意思是什麼
-
So, developing expander board for simulation become important the function of expander board is joint between the data bus of pc and the data bus of aviatic electronic system, and operation aviatic electronic system under the control of pc instruction. pc could simulate aviatic electronic device on the ground
擴展板的重要任務是將專用航電系統的數據總線與pc機的數據總線連接起來，並且依據pc機的指令而操作總線上的子系統，這樣pc機就可在地面上模擬飛機上的慣導系統，火控系統等等。 -
Secondly, the composition and function of expander board is introduced, the paper describes a detail developing process of selecting component, design interface circuit, protract pcb with protel and design pci interface logic and user ' s logic. with ahdl and max + plus. in addition this paper discusses how to debug pci board, and give the simulation waveform and the result of debug. on the base of all functions is ture, this paper introduce the config registers and memory of bu - 61580, realize the interrupt function and communication based on mil - std - 1553b
首先分析了擴展板的組成、功能，對pci介面邏輯和擴展板的內部邏輯進行詳細設計，並根據其資源要求進行器件選擇，然後使用protel工具進行電路板的製作。另外，本文還介紹了擴展板的調試方法，給出了邏輯模擬波形和調試結果。在此基礎上，本文闡述了協議晶元的配置方法，實現了1553b通訊擴展板間的通訊及中斷功能，達到了開發技術指標。 -
In this thesis, the interface between pc and expander board adopt pci bus architecture
本課題中擴展板與pc機的介面採用流行的pci總線體系結構。
