Generator of graphics in computer system

Image Number 3 for United States Patent #6930688.

An apparatus for generating graphics is connectable in a computer system between a system processor and a system memory by way of a data bus. The apparatus comprises two registers for the storage of X and Y coordinates respectively of a single pixel. The coordinates are applied to an address conversion calculation unit for calculating a linear memory address corresponding to the pixel coordinates and the data representative of the pixel is stored in the system memory at the calculated address. The two registers are memory mapped to appear at two or more locations in memory such that operation of the apparatus is dependent on the memory location used by each register. The apparatus carries out many of the repetitive operations required in the generation of graphics.
