    摘要: A method and apparatus for producing a fragment descriptor for use in oversampling anti-aliasing includes processing that begins by generating a single representative color value for a plurality of subpixels of a pixel. The processing then continues by generating a single representative Z value for the pixel. The processing continues by generating masking information for the pixel, wherein the masking information indicates, for a given object-element being rendered, coverage of the pixel by the object-element. The processing continues by packing the single representative color value, the single representative Z value, and the masking information into a fragment descriptor. The processing continues by transporting the fragment descriptor to a custom memory. When the custom memory receives the fragment descriptor it unpacks it to recapture the single representative color value, the single representative Z value and the masking information. The custom memory then duplicates the single representative color value for each subpixel of the pixel that is covered by the object-element based on the masking information. The custom memory then determines slope information for the pixel such that Z values may be determined for each subpixel. In addition, the custom memory generates color values and the Z values for each subpixel.

    摘要: A method and apparatus for graphics processing that utilizes multiple graphics processors in parallel is presented. A primary graphics processor is operably coupled to a primary memory that includes a primary color buffer and a primary Z buffer. The primary processor processes a first portion of the image data for a frame, where processing the first portion stores color data in the primary color buffer and Z data in the primary Z buffer. A secondary processor is operably coupled to a secondary memory that includes a secondary color buffer and a secondary Z buffer. The secondary processor processes a second portion of the image data for the frame. The processing of the second portion of the image data results in color data being stored in the secondary color buffer and Z data being stored in the secondary Z buffer. The display signal that results in the image data for the frame being displayed is generated by a display driver included in the primary processor. In one embodiment, the display driver retrieves all of the color data used to generate the display signal from the primary color buffer. As such, the secondary processor transfers the color data for the second portion of the frame from the secondary color buffer to the primary color buffer to facilitate generation of the display signal. This data transference preferably occurs utilizing direct memory access (DMA) transfers that may be initiated during the vertical blanking interval portion of the display signal.

    摘要: A method and apparatus includes a real time event engine that monitors event signals. A real time event detector within the real time event engine detects when the real time event occurs. Thereupon, real time event commands within a real time event command buffer are fetched and consumed by the command processor in response to the occurrence of the real time event. The real time event detector contains a plurality of control registers, which contain an event selector register, a real time command buffer point register, and a real time command buffer length register. A driver may program the registers, whereupon a singe real time event detector may be used in conjunction with a plurality of real time event command buffers.

    摘要: A method and apparatus for multipass pixel processing is presented. A command stream that includes a plurality of drawing commands is received where multipass drawing commands included in the stream include a number of sets of state information and one or more graphics primitives. For a multipass pixel processing operation, the graphics pipeline that performs the pixel processing is first configured using a first set of state information included in the sets of state information for the multipass operation. Once the graphics pipeline has been configured, at least a portion of the processing to be performed for the drawing command is performed using the graphics pipeline as configured by this first set of state information. The resultant data produced through this processing is stored as intermediate data. This may be referred to as the first pass in the multipass operation. The graphics pipeline is then reconfigured using a subsequent set of state information corresponding to the multipass drawing command. Once the graphics pipeline has been reconfigured, the second pass takes place. The second pass includes processing the portion of the graphics data processed during the first pass using the graphics pipeline as configured by the subsequent set of state information. Such processing includes utilization of the intermediate data such that the results of the first pass are included in the processing operations of the second pass.

The apparatus and method also includes solely performing early Z processing for subsequent pixels entering the pixel pipeline responsive to determining that late Z processing for the one or more pixels currently in the pixel pipeline has been completed. The methods and apparatus, facilitates concurrent processing of early and late Z data to avoid flushing portions of the pixel pipeline.
