基于FPGA的P2020处理器显示接口设计

摘要

针对目前使用的飞思卡尔高性能通信处理器P2020无内置LCD控制器，不方便在某些需要显示界面的中小设备中直接应用的问题，提出了基于CPU＋FPGA的显示接口设计方案，给出了硬件原理框图、FPGA逻辑实现原理框图以及设计结果，在项目中成功应用并满足需求。%Aiming at the problems caused by the most of the high -performance communication processor,which has no built-in LCD controller and is not convenient to be used in some middle and small size communication apparatus for display interface,a new design of the display interface based on CPU +FPGA is described in this paper.It provides the block diagram of hardware,FPGA logic block diagram and achievement results,which are successfully applied in the project to meet the requirements.
