1. Introduction:

This is a highly versatile on-screen display that allows high-quality anti-aliased bitmap graphics to be inserted over RGB video. The module supports a wide range of graphics effects and the programming interface is very simple to use. The bitmap overlay is partitioned into an array of tiles which are addressed by means of an 8-bit value stored in a 64x64 tile buffer. There are four tile sizes available - either 8x8, 16x16, 32x32 or 64x64.

The tiles in the buffer are displayed in a graphics window which may be positioned anywhere within the display area. Bitmaps for each tile are stored in a user-defined ROM which can contain up to  256  different bitmaps stored over three bit-planes. Depending on the chosen graphics mode, the 3-bits per pixel may be used to select one colour from a palette of eight, eight levels of alpha transparency or seven colours on a transparent background.

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