As a result , this design accomplishs the function of circuit , which not only can satisfy the high speed image data transmission of large screen system and improve the performance of circuit , but also increase the flexibility of circuit design . in the design , it is possible to act hardware description language procedure according to the practical application demand , instead of revising hardware design of the circuit , which reduce the design cycle and the cost 所以,本課題運用可編程邏輯器件來完成電路功能,不僅能夠滿足大屏幕系統(tǒng)高速圖像數(shù)據(jù)傳輸對速度的要求,改善了電路性能,而且增加了電路設(shè)計的靈活性,設(shè)計中可以根據(jù)實際應(yīng)用的需求靈活修改相應(yīng)硬件描述語言程序,而不需要修改電路硬件設(shè)計,縮短了設(shè)計周期,降低了成本。
The methods of adopting fpga to realize the function of counter , and adopting verilog hdl hardware description language to design every function modules , not only makes the whole design more compact and stable , but also make the alteration of the circuit ’ function merely need to alter the software according to the practical task requires , and needn ’ t alter the hardware connection of the circuit 在計數(shù)器功能的實現(xiàn)上采用fpga ( fieldprogrammablegatearray ) ,利用veriloghdl ( hardwaredescriptionlanguage )語言編寫了各個功能模塊,不僅使整個設(shè)計更加緊湊、穩(wěn)定且可靠,而且可以根據(jù)實際的任務(wù)要求,在無需改變硬件電路板的情況下,通過修改硬件描述語言程序,即可修改電路功能。
