<h1>OSD_V4_0</h1>
<p>
This is main header file of the Xilinx On-Screen-Display (OSD) core.<p>
An OSD is an image superimposed on a screen picture, commonly used by modern televisions, VCRs, and DVD players to display information such as volume, channel, and time.<p>
Xilinx OSD core has the following main features:<p>
<ul>
<li>Read Video Data from one of three sources as<ul>
<li>VFBC/Frame Buffer,</li><li>VideoBus and</li><li>Graphics Controller.</li></ul>
</li><li>Alpha Compositing and Alpha Blending of up to 8 layers.</li><li>Up to 8 priorities, one for each of the layers.</li><li>Real-Time Graphics Controller.</li><li>Write Composited Video Data to either<ul>
<li>VFBC/Frame Buffer, or</li><li>VideoBus.</li></ul>
</li></ul>
<p>
For a full description of OSD features, please see the hardware spec.<p>
<b>Interrupt Service </b><p>
Three interrupt types are supported:<p>
<ul>
<li>Processing Start Interrupt</li><li>Frame Done Interrupt</li><li>Error Interrupt</li></ul>
<p>
