基于FPGA的ARM图像扩展显示

摘要

ARM处理器在消费电子及仪器设备等领域得到了广泛的应用,但是在很多情况下ARM系统的图像分辨率支持偏低,通过使用FPGA实现图像缩放器的功能来解决这个问题.采用双线性插值算法将VGA格式的ARM9图像信号的转换为XGA格式图像信号,完成对分辨率的扩展.仿真验证证明,扩展后的图像在显示上取得了良好的效果.%ARM processor is widely used in the field of consumer electronics and instrumentation, but the disadvantage of ARM processor is low resolution in image resolution in many cases. We solve the problem by using FPGA to implement sealer, which can transform the VGA standard image provided by ARM to the XGA standard image by use bilinear interpolation. The results show that the expanded image has a good display by simulation and verification.
