摘　　要：针对SOPC Builder系统没有提供TRDB-LTM液晶模块驱动的问题,提出了一种基于Avalon总线的TRDB-LTM控制器IP核设计,并构建了基于NiosII嵌入式处理器的片上系统。整个系统在Altera公司的DE2-70板上实现与验证。实验表明该IP核可显示多种图形、图像、文字,并可实现动画效果,具有一定的实用价值。设计采用Avalon总线多主控的方式来提高数据的传输效率,减少系统资源的消耗。For the problem that there is no TRDB-LTM module driver in SOPC Builder system,a TRDB-LTM controller IP core based on Avalon is proposed and a SOC based on Nios II embedded processor is constructed.The entire system is implemented and verified on Altera DE2-70 development board.The experimental results show that the IP core could display many kinds of graphs,images and characters and realize animation effect,thus is of certain practical value.An Avalon Bus multi-master control is adopted to improve the data transmission efficiency and reduce the system resource consumption.
