A system and method for controlling memory accesses for display data. Pixel data for a display are accessed by a graphics controller having two linear counters, the first counter controlling which column is accessed by the controller, the second counter controlling which row is accessed by the controller. With each successive memory access within a predetermined set of accesses, the first counter increments. When the first counter reaches the end of the row in memory (or another predetermined counting state), the second counter increments. When the second counter increments, the controller necessarily accesses the next row of memory locations.
