ABSTRACT:
A graphics processing system allows for fuller utilization of memory space by allowing freedom in performing X-Y conversions to linear addressing for graphics display. The system takes advantage of the fact that many display pitch dimensions can be defined in terms of powers of 2, thereby allowing for simple shifts in the binary value followed by an addition of two such shifted numbers. For non-even situations full multiplication by the pitch is available. This operation is controlled by the values in two registers, which values in turn control the actual shifting and multiplication functions.
