基于FPGA驱动 高速点阵板驱动系统及相关接口研制 FPGA-based high-speed dot matrix driver board drive system and related interfaces are developed Pan Maosheng Summary： Paper based on todays popular LED control technology industry to the core of the new controller FPGA board high-speed dot-matrix driving scheme, the paper describes the development of LED screens in the domestic situation and prospects of China with good technical and industrial chain of LED controller has not underestimate the significance, combined with dot-matrix screen features to determine the control scheme of the paper and the FPGA integrated parallel scan. Second, LED dot matrix board composed of three chapters introduce the basic principles of light and human visual characteristics, introduced three LED drivers to discuss the program and obtained pulse-driven program has a great advantage. Chapter IV introduces the basic principles of FPGA, Altera FPGA and most popular devices EP2C5T144C8N, introduced the popular FPGA development tool Quartus Ⅱ, NIOS Ⅱ and ModelSim, FPG development process and development features, and introduces the popular features of the hardware description language Verilog HDL . Lattice board chapter combines elements of the design principle and control scheme, designed to improve the transmission efficiency of Data Organization. It focuses on Chapter VI, describes the various software modules and hardware modules of the composition and combination of methods, combined with dot-matrix plates and its features to determine the purpose of realization of the controller, the system design for the concrete implementation, the module works detailed description of Verilog HDL description of the module, IP core use, the combination of hardware and software modules and debug the debugging process simulation results, and ultimately to achieve the design requirements. Chapter VII of the hardware design of the structure, the basic components of each module and module combination. Chapter VIII of the combina
