Alpha-Blender中文资料FPGA IP Cores数据手册Microchip规格书

描述 Description

Alpha-blenders play an important role in many video processing systems. They are primarily used when some portion of two video sources must be viewed at the same time. Where a simple MUX allows data from only one input source to be passed, an alpha-blender permits blending of the two sources for an eye-pleasing result. FPGA resources can be quickly consumed by an alpha-blender due to the multiplication and addition associated with its function. Attodyne took measures to optimize the Alpha-Blender Core for minimum resource usage. One of these measures is limiting the alpha-blending to 4 levels: 25, 50, 75, and 100%, which will satisfy most applications. The Alpha-Blender Core can be used in On-Screen Display (OSD) applications to give a transparent look to the overlay. Other examples include picture-in-picture, telemetry overlays, and touch-screen feedback systems.
