摘要
提出了一种基于CPLD的彩色模拟TFT-LCD驱动板的设计方法。在划分各个功能模块的基础上,一方面阐述了该设计方法的核心芯片设计原理;另一方面详细描述了CPU与CPLD之间控制逻辑的设计,同时根据实际情况选择了协调CPU与LCD的仲裁协议方案。芯片在QuartusII环境下使用VHDL编程、仿真,最终成为某公司无纸记录仪的一个关键部件。
A design method of a color analog TFT- LCD driver board based on CPLD is put forward. Based on each functional module, the core - chip design theory is presented and the control logic between CPU and CPLD is described in detail. The arbitration protocol for the tune between CPU and LCD is determined by practice. The chip is programmed and simulated by VHDL in QuartuslI, wlaich final product will be a key part of a company＇ s paperless recorder.
