基于Avalon-MM突发传输的LCD控制器的设计与实现

Design and implementation of LCD controller based on Avalon-MM burst transfer

针对不同液晶显示器(LCD)规格导致的驱动差异,提出一种LCD显示控制器的可编程片上系统(SOPC)系统架构,并完成了该架构的软硬件实现。设计基于Avalon主端口突发传输方式,采用参数化设计方法,实验证明,所设计的LCD控制器能够满足较高分辨率的要求,可以运用于不同型号的LCD。

Aiming at the difference of drivers among kinds of LCD, architecture of a LCD controller with SOPC （ System On a Programmable Chip） technology was introduced and implemented in this paper. The design with the adoption of parameterization technology is based on the Avalon-MM （ Memory Map） master burst transmission mode. The experiment shows that the LCD controller can satisfy LCD display with high resolution, and can be applied to many kinds of LCD, having extensive application prospect.
