Abstract
In one embodiment, the invention is an apparatus. The apparatus includes a Z-buffer memory. The apparatus also includes a set of bits, each of which corresponds to a block of the Z-buffer memory. The apparatus also includes an initialization (init) register. The apparatus also includes control logic coupled to the Z-buffer memory, the set of bits, and the init register. The control logic sets the set of bits upon receipt of an initialization request. The control logic retrieves a Z value from either the init register or from the Z-buffer memory according to the states of the set of bits.
