摘要

针对便携式仪器仪表对彩屏液晶显示器件依赖性逐渐增强的现状

设计并研制了以Xilinx公司生产的型号为XC3S400的FPGA芯片为硬件核心

以嵌入式8051 IP核为时序控制核心的TFT-LCD实时显示控制器。采用FPGA内部的Block RAM资源对内核需要的存储器模块进行初始化配置

采用异步FIFO实现FPGA采集到的高速数据流与IP核处理速度之间的速率匹配。控制器具有较强的通用性

可以适用于多种型号液晶的控制

应用空间广阔。

Abstract

According to the fact that portable instrument has more and more reliance on colo-rized LCD displaying devices

a TFT-LCD real-time display controller is designed in this paper. The controller adopts FPGA chips as its hardware core

which is a product XC3S400 of Xilinx Corporation

and embedded 8051 IP core is used as its time control kernel. Internal block RAM resource of FPGA is introduced to initially configure the memory modules needed by IP core. Asynchronous FIFO is applied to realize the speed matching between high speed data flow acquired by FPGA and the slow processing speed of IP core. The controller has a wide range of application

and it can be applied to a variety of LCD

so it has a broad space of usage.
