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。 In view of the fact that the SOPC Builder system does not provide the driver of the TRDB-LTM LCD module, a design of the TRDB-LTM controller IP core based on the Avalon bus is proposed and a system-on-chip based on the NiosII embedded processor is constructed. The entire system is implemented and verified on Altera’s DE2-70 board. Experiments show that the IP core can display a variety of graphics, images, text, and can achieve animation, has some practical value. The design adopts Avalon bus multi-master way to improve the data transmission efficiency and reduce the system resource consumption.
