The research of this task comes from key projects in scientific research of the tenth " five - year plan " ( ( the technology of color spray - paint graph plotter for military use ) ) . a further study has been made of pci2 . 2 bus protocol , and a theoretical summarization of the protocol needed in the design of pci system is presented from the viewpoint of engineering application . . on the basis of a good knowledge of pci bus protocol , this paper suggests a new method of data transmission based on pci on high - speed spray - paint graph plotter , and then designs hardware logic according to the methed , puts pcb board into practice . finally , the wdm drive progam of the hardware device is designed
論文深入研究了pci2 . 2總線協(xié)議，并在工程角度上對pci總線協(xié)議中項目相關(guān)的協(xié)議的進行了理論總結(jié)。本論文在深刻理解pci總線協(xié)議的基礎(chǔ)上，提出了高速大幅面新一代彩色噴墨繪圖機上基于pci數(shù)據(jù)傳輸技術(shù)的一種新穎的解決方案，并基于這種方案設(shè)計出硬件邏輯，實現(xiàn)pcb板，最后設(shè)計出該硬件設(shè)備的wdm驅(qū)動程序。本文在設(shè)計硬件邏輯時，擺脫了傳統(tǒng)設(shè)計思路，應用了一種新穎的設(shè)計方法，應用了quicklogic公司的嵌入式可編程接口芯片q15030來完成接口芯片設(shè)計。
