摘要： A graphics processing system comprises at least one memory device storing a plurality of pixel command threads and a plurality of vertex command threads. An arbiter coupled to the at least one memory device is provided that selects a pixel command thread from the plurality of pixel command threads and a vertex command thread from the plurality of vertex command threads. The arbiter further selects a command thread from the previously selected pixel command thread and the vertex command thread, which command thread is provided to a command processing engine capable of processing pixel command threads and vertex command threads.

摘要： A method and apparatus for graphics processing using state and shader management includes at least one state and shader cache coupled to a compiler for compiling a hardware state and shader vector from an abstract state vector. Also included is an abstract state vector register containing the abstract state vector that is provided to the state and shader cache and the compiler. The state and shader cache receives the abstract state vector and determines whether a cache entry for that abstract state vector already exists. If the cache entry exists, the hardware state and shader vector is provided to hardware. If the entry does not exist, the state and shader cache provides a miss signal to the compiler, whereupon the compiler compiles the abstract state vector and generates a hardware state and shader vector. Thereupon the hardware state and shader vector is provided to the hardware.

摘要： A method and apparatus for ensuring data coherency in a processing system that includes shared memory is presented. This is accomplished by including a hierarchical validity database within the core logic that interconnects the various memory clients to the memory structure. The hierarchical validity database stores a number of hierarchical levels, where each level pertains to different sized portions of the memory. Validity of a portion, or block, within the memory can be determined by referencing the hierarchical validity database.

摘要： The method provides for sort independent alpha blending of fragments of a graphic image. A sequence of fragments has opaque fragments and transparent fragments. The opaque fragments are rendered to a frame buffer having at least a z buffer, the z buffer having stored therein z values of front most opaque fragments. Transparent fragments are stored in a list in a transparent fragment buffer. The transparent fragments are sequentially read from the list and are discarded if they are occluded by an opaque fragment. When not occluded, the transparent fragments are stored in a list. The z buffer is cleared and the transparent fragments are read sequentially from the list. Z values are stored in the z buffer for back most transparent fragments. The transparent fragments are again sequentially read from the list. Z values of currently read transparent fragments are compared to z values in the z buffer of corresponding fragments. If a currently read transparent fragment is a back most transparent fragment, then it is rendered with alpha blending to the frame buffer, otherwise it is again stored in the list. This process is repeated beginning with the clearing of the z buffer until the list is empty.

摘要： A video graphics system that includes a graphics processing circuit and a logic enhanced memory is presented. The logic enhanced memory includes an operation block that performs blending operations for fragment blocks received from the graphics processing circuit, where the fragment blocks include pixel fragments generated by rendering graphics primitives. In order to allow limited bandwidth buses that transport data between the graphics processing circuit and the logic enhanced memory to be used with maximum efficiency, an input buffer and an output buffer are included in the logic enhanced memory. A graphics processing circuit maintains history data that indicates how full the input and output buffers of the logic enhanced memory are, and as such, can ensure that new fragments blocks and operational commands are not provided to the logic enhanced memory in a manner that would cause the processing capabilities of the logic enhanced memory to be exceeded.

摘要： A method and apparatus for antialiasing in a video graphics system is presented. This is accomplished by determining if a pixel sample set, which results from oversampling, can be reduced to a compressed sample set that includes a single color value and a single Z value that fully describes a corresponding pixel. When the pixel sample set can be reduced to the compressed sample set, the compressed sample set is stored in a frame buffer at a location corresponding to the particular pixel that the sample set describes. When the pixel sample set cannot be reduced to a compressed sample set, pointer information is stored at the frame buffer location corresponding to the particular pixel. The pointer information includes a pointer that points to a selected address in a sample memory at which the complete sample set for the pixel is stored. The pointer information may also include a front most Z value corresponding to the sample set such that some pixel fragments to be blended can be discarded without referencing the sample memory.

摘要： A method and apparatus for processing object elements as they are being rendered begins by comparing geometric properties (e.g., the Z value) of at least one object element with a representative geometric property for a group of pixels. The group of pixels is determined based on physical coordinates (i.e., the coordinates of a display) that are inclusive of the physical coordinates of the object element. When the comparison of the geometric properties of the object element compares unfavorably with the representative geometric property for the group of pixels, the object-element is rendered and a Z buffer is updated with new Z buffer information. At a given point during the rendering of the object-element, a new representative geometric property is determined based on the updated Z value. Once the new representative geometric property is determined, the representative geometric property is updated with that new value.

摘要： A method and apparatus for antialiasing in a video graphics system is accomplished by determining if a pixel sample set, which results from oversampling, can be reduced to a compressed sample set, where the compressed sample set contains information describing a corresponding pixel. When the pixel sample set can be reduced to a compressed sample set, the compressed sample set is stored in a frame buffer at a location corresponding to the particular pixel that the sample set describes. When the pixel sample set cannot be reduced to a compressed sample set, a pointer is stored at the frame buffer location corresponding to the particular pixel. The pointer points to a selected address in a sample memory at which the complete sample set for the pixel is stored. When the sample memory reaches capacity, storage of the complete sample set in the sample memory is reduced to a subset of the complete set, allowing all pixels in each frame to be accommodated, but removing the loss-less characteristic of the compression technique.
