【摘要】 由于LCD种类繁多,接口又各不相同,因而给LCD控制器的设计带来重复性设计问题。文章通过对LCD控制器的各功能模块进行了合理划分,将其关键的,也是各个LCD控制器的共同部分定义成中央控制单元,并将其设计成参数化的IP,具有很好的移植性。同时,提出了用FIFO电路来解决显示存储器并发访问和异步时钟域问题,即使在极端工作条件下,也能获得很好的画面质量,对于各种LCD控制器的设计都有很好的参考价值。更多还原

【Abstract】 Various kinds of LCD and their various interfaces lead to repeated design for the LCD controller. In this paper, function modules are rationally classified, the key parts, which is the common parts, are defined as the central control unit and designed as the parametrical IP that has highly reusable. In the mean while, the solution to concurrent access of the display storage and asynchronous clock are brought out through FIFO circuit. Even though on the excessive working environment, the picture quality is good. This paper has good consulting value to design any LCD controller.更多还原
