Graphics Processor Overlay IP Core
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 defined in a ROM which can contain up to 128 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. There is also a feature to highlight a tile with a background colour. This is especially useful for interactive text-based menus and lists where the user has to select an option.
Pixels flow in and out of the overlay module in accordance with a simple streaming (valid/ready) protocol. Pixels and syncs are sampled at the module inputs on a rising clock-edge when pixin_val is high and pixin_rdy is high. Likewise, pixels and syncs are transferred out of the module on a rising clock-edge when pixout_val and pixout_rdy are asserted high. The streaming protocol allows both input and output interfaces to be stalled independently.
The streaming protocol is very versatile and permits any number of GPU overlay modules to be cascaded in series. By placing more than one module together, the user is able to achieve more complex text and graphics displays with different fonts and colours.
