AbstractA rasterizer, particularly suited for generating patterns for semiconductor masks and the like is described. An 8×8 array uses RAS, CAS and WE signals in addition to the memory address for accessing the array. A state machine is used to convert the pattern data (e.g., type of object orientation, etc.) into accessing data with the WE generator being driven through a ROM.
