ABSTRACT:
Stored data for two different images superimposed on one another can be accessed simply and efficiently from the same VRAM. The SAM of the VRAM is divided into multiple-independent portions, each of which respond to its own independently controlled address counter. By loading the image data access into respective SAM portions, and switching data access between SAM portions at the SAM address rate, superimposed data of two different images can be displayed from the same VRAM.
