| Abstract: | This paper has proposed a design method for SOPC of LCD driver based on FPGA. In the system of SOPC, FPGA is the core controller, NiosII embedded into an EP3C25F324C8Z of Altera CycloneIII series, and peripheral driving circuit designed. Combining modular design ideas and rich logic resources of FPGA, this paper has designed SDRAM module, FLASH module, VGA module, PLL module and other IP soft cores, which are integrated into a piece of FPGA. The LCD driver control with 640×480 dots is realized. The correctness and feasi- bility of FPGA-based hardware design have been verified by debugging. |
