摘 要: GC3210是基于中科院计算所龙芯IP核的一款低功耗、低价格、高性能的嵌入式处理器,不支持VGA接口,无法与通用显示设备进行连接,采用FPAG或ADC实现VGA输出,成本太高,市场无法接受。文章根据市场应用的实际情况提出了一种基于GC3210处理器的LCD转VGA接口的低成本设计方案,讨论了LCD转VGA的总体设计,验证了方案的可行性,在验证过程中改进了方案。方案设计巧妙、成本低廉,已经在Thin Client产品中得到很好的应用,取得了很好的效果。 GC3210 is a low-power,low cost,high-performance embedded processor based on the IP core of Godson developed by the Chinese Academy of Sciences.But it does not support VGA interface,can not be connected with common display devices.The paper presents a new design of low-cost LCD2VGA program based on GC3210 processor,program design of the LCD2VGA,and verifies feasibility of the program.The program has been verified to be good in the application of Thin Client products.
