【摘要】 介绍了基于CPLD液晶显示屏控制系统的设计方法,并详细介绍了用VHDL硬件描述语言设计行,场液晶显示时序与控制的方法。并给出了帧存取控制的仿真结构图。该控制显示系统已成功运用在某型直升机惯导显示系统中。通过实际测试和评估,该控制系统运行良好,证明该设计方法十分有效。更多还原

【Abstract】 To design the control system of LCD,a method based on CPLD is described,including the means of designing the horizontal sync signal and the vertical sync signal with VHDL.And the mothed of storage and access of data frames in RAM is also stress,giving out the structure of HDL(hardware describle language) program.This control system has been used in the display system of intertial rangation in some kind of helicopter.In result this method is proved effective after evaluation.更多还原
