Abstract: 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 command thread from either the plurality of pixel or vertex command threads based on relative priorities of the plurality of pixel command threads and the plurality of vertex command threads. The selected command thread is provided to a command processing engine capable of processing pixel command threads and vertex command threads.

Abstract: A graphics processing system comprises a command processing engine capable of processing pixel command threads and vertex command threads. The command processing engine is coupled to both a renderer and a scan converter. Upon completing processing of a command thread, which may comprise a pixel command thread or a vertex command thread, the command engine provides the command thread to either the renderer or the scan converter.

Abstract: A device and method for controlling generation of a final pixel utilizes a conditional statement, referred to as an IF_NEIGHBOR statement, which when compiled, causes a programmable pixel shader to perform mip map texture lookups even if a pixel of interest does not meet the condition of the conditional statement. As such, any neighboring pixels needed for mip map selection have their associated shader code guaranteed to execute even though the pixel of interest may fail the conditional portion of the conditional statement. The device and method executes texture address calculations for pixels within a region and for pixels outside of a region but only those necessary to determine the mip map level corresponding to a pixel within the region. Execution of shader code for a current pixel is executed if any of the surrounding neighboring pixels meet the desired condition even if the current pixel does not meet the condition.

Abstract translation: 用于控制最终像素的生成的装置和方法利用称为IF_NEIGHBOR语句的条件语句，其被编译时，使可编程像素着色器执行mip映射纹理查找，即使感兴趣的像素不满足 条件语句。 因此，即使感兴趣的像素可能会失败条件语句的条件部分，mip映射选择所需的任何相邻像素也保证其相关联的着色器代码执行。 该设备和方法对区域内的像素和区域外的像素执行纹理地址计算，而仅对确定与该区域内的像素对应的mip地图级别的那些进行纹理地址计算。 即使当前像素不符合条件，任何周围的相邻像素都满足所需条件，则执行当前像素的着色器代码。

Abstract: A method and apparatus for interpolating pixel parameters based on the plurality of vertex values includes operating first and a setup mode and a calculation mode. The method and apparatus includes, while in a setup mode, generating a plurality of differential geometric values based on the plurality of vertex values, wherein the differential geometric values are independent of a parameter slope between the plurality of vertex values. While in a calculation mode, a first geometric value and second geometric value are determined based on a pixel value, a plurality of vertex values and the differential geometric values. A pixel value is determined for each of the plurality of pixels based on the vertex parameter value, the first geometric value and the second geometric value. Thereupon, pixel parameters may be interpolated on a per-pixel basis reusing the differential geometric values.

Abstract: The present invention includes a multi-thread graphics processing system and method thereof including a reservation station having a plurality of command threads stored therein. The system and method further includes an arbiter operably coupled to the reservation station such that the arbiter retrieves a first command thread of the plurality of command threads stored therein such that the arbiter receives the command thread and thereupon provides the command thread to a command processing engine. The system and method further includes the command processing engine coupled to receive the first command thread from the arbiter such that the command processor may perform at least one processing command from the command thread. Whereupon, a command processing engine provides the first command thread back to the associated reservation station.
