Abstract
The invention concerns loading data into VIDEO RAM in a computer. A processor delivers data to VIDEO RAM by using 'STRING OPs,' which are data-copying operations wherein a field of consecutive data words is copied from one location (such as character memory) to a range of consecutive addresses at another location (such as VIDEO RAM). The invention intercepts the words intended for the consecutive addresses, and distributes them into VIDEO RAM at evenly spaced, non-consecutive addresses. When a graphics controller generates pixels on a display, based on these evenly-spaced addresses, the pixels will automatically occupy a vertical column on the display.
