Design And Implement Of Data Transmission System Based On FPGA On PCI Bus On High-speeded Gragh Plotter

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.We propose a novel method of designing PCI interface,which gets of the traditional design idea,and apply the embedded programmable chip of Quicklogic company, i.e . QL5030, to implement the design of the interface chip.The PCI interface controller and programmable logic were integraed in QL5030 chip.On the basis of the profound comprehension of PCI protocol,we designed the bus configuration ,data transision logicand self-test logic by using the languge such as VHDL.Verilog. In the process of design, simulation is achieved by Active HDL,and synthesis is achived by Symplify, and finally the chip is downloaded in QuickPro.Finally,a brief solution of WDM dirver program,specially the one based on PCI is presented in this paper.The paper has successed in designing the WDM driver program of the hardware above,a simple application is also presented here.The function model designed in this paper will be applied in the key projects in scientific research of the Tenth "Five-Year Plan" 《The technology of color spray-paint graph plotter for military use》 .
