The design manual welding in his simple FPGA board implemented, and in QusrtusII using VHDL nc prescaler circuit design, using CNC dividing principle design music hardware play circuit, and formulate LPM-ROM storage music data, to "butterfly lovers" music as an example, music data storage to LPM-ROM, it reached the pure hardware means to accomplish the music playing effect, as long as modified LPM-ROM stored in the music data, change it for the rest of the music data, then re-enacted LPM-ROM, then linked to program can realize its function and play design USES the FPGA the chips for the FLEX of ALTERA company series EPF10K10LC84-4. Because board is himself in the multi-purpose board welding so only the necessary peripherals such as welding and LED a buzzer.

Abstract of a thesis: Over the past 2007, break out and spread rapidly to the whole world since time of American loan crisis is all-round, secondary begin to initiate a series of the whole world financial turbulence, to the at last produces heavy effect to the real economy. With the fact that stock market slumping , credit contracts , real estate gets lost low, investor confidence glides or collapses, the lot of developed country and the few emerging market country are caught in a decay numerously and confusedly , world economy steps into the obvious risk go up being at a standstill declining even. The industry city undergoes all kinds of impact but one by one under big background unifying in world economy whole world, although financial crisis differs to the effect size that economy brings about in every country, has the tourist trade fitting of "there being no cigarette estate and sunrise industry " among them because of the person has altitude therefore the sex being connected and the sex opening to the outside world, looking like that the altitude especially, pushing our forward, and arousing pays close attention to and takes seriously. The international financial crisis the main body of a book is studied by analysis causes effects on Dong Guan City tourist trade, Announce to our opportunity being there are still by what challenge that the tourist trade being in economy rotating Dong Guan City that the type expects brings about, what to contain among them in this crisis thereby. Accordingly work out and perfect whose tourist trade develops strategy and the strategic objective in the future, feasible Dong Guan City tour resource gets sufficient rational making use of , is Dong Guan City economic recovery thereby and boosts structure of all-round , be in harmony , sustainable development and harmonious economy society founding a capital up having arrived at prop up an effect and extremely far-reaching important effect significance.希望能帮到你哦~~：）
