1. 概述：

The IP Core is a highly versatile On Screen Display (OSD) module that allows text and bitmap graphics to be inserted over RGB video.   The module supports a wide range of text effects and the
programming interface is very simple.  Text is written to a 64x32 character buffer which is mapped (via a bitmap ROM) directly to the display.

The characters in the buffer are displayed in a 'TEXT BOX' which may be positioned anywhere in the video display area. Bitmaps for each character are stored in a ROM which may be modified to support different font styles or bitmap graphics.

Pixels and syncs flow in and out of the overlay module in accordance with the valid-ready pipeline protocol.
