学术论文  用FPGA实现“共轭变换”图像处理方法

近年来微光、红外、X光图像传感器在军事、科研、工农业生产、医疗卫生等领域的应用越来越为广泛，但由于这些成像器件自身的物理缺陷，视觉效果很不理想，往往需要对图像进行适当的处理，以得到适合人眼观察或机器识别的图像。因此，市场急需大量高效的实时图像处理器能够在传感器后端对这类图像进行处理。而FPGA的出现，恰 ...

单片机编程  Input Signal Rise and Fall Tim

All inputs of the C16x family have Schmitt-Trigger input characteristics. These Schmitt-Triggers are intended to always provide proper internal low and high levels, even if anundefined voltage level (between TTL-VIL and TTL-VIH) is externally applied to the pin.The hysteresis of these inputs, howeve ...
