ABSTRACT:
A main memory comprises one or more memory devices which include logic for performing a predetermined graphics operation upon graphics primitives stored therein. The microprocessor(s) within the computer system may direct the memory to perform the predetermined operation upon the graphics primitives instead of performing the operation within the microprocessor(s). If the graphics primitives are stored into multiple memory devices, each memory device operates upon the graphics primitives stored within that memory device in parallel with the other memory device's operation. Accordingly, the bandwidth is a linear factor of the number of memory devices storing graphics primitives. In one embodiment, each memory device iteratively performs the predetermined operation upon the set of graphics primitives stored in that memory device. Because the memory device is iterative, logic for performing the predetermined graphics operation upon one graphics primitive at a time may be employed. The memory devices are also operable as passive memory devices if no graphics primitives are stored therein. Accordingly, at times in which video processing is not being performed, the memory devices may be used to store instructions or other data.
