  • Method and apparatus for Z-buffer operations
    Patent number: 7333106
    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.

  • 3-D graphics chip with embedded DRAM buffers
    Patent number: 6937242
    Abstract: A 3-D graphics chip includes independent internal DRAM buffers each having a wide bandwidth access bus for connection to a 3-D texture rendering drawing engine. The 3-D drawing engine takes advantage of a flexible embedded memory interface to reduce the traditional 3-D pipeline delay by a factor of 3. In a specific embodiment, each of three drawing processes—texture, Z, pixel—retrieves and stores information in a separate embedded drawing buffer via separate wide bandwidth access busses. Access to an external memory is provided via a separate external access bus. In another specific embodiment, the 3-D drawing engine accesses the embedded drawing buffers via read and write FIFO's to maximize the drawing process throughput.
