摘要： A method, computer program product, and computing system are provided for processing a graphics operation. For instance, the method can include receiving the graphics operation from an application. The method can also include allocating a first portion of the graphics operation to a first processing unit and a second portion of the graphics operation to a second processing unit. This allocation between the first and second processing units can be based on at least one of a performance profile and a functionality profile of the first and second processing units.

摘要： A method resumes an accelerated processing device (APD) wavefront in which a subset of elements have faulted. A restore command for a job including a wavefront is received. A list of context states for the wavefront is read from a memory associated with a APD. An empty shell wavefront is created for restoring the list of context states. A portion of not acknowledged data is masked over a portion of acknowledged data within the restored wavefronts.

摘要： A method tolerates virtual to physical address translation failures. A translation request is sent from a graphics processing device to a translation mechanism. The translation request is associated with a first wavefront. A fault notification is received within an accelerated processing device (APD) from the translation mechanism that a request cannot be acknowledged. The first wavefront is, stored within a shader core of the APD if the fault notification is received. The first wavefront is replaced with a second wavefront if the fault notification is received, the second wavefront being ready to be executed.

摘要： A method and apparatus for sequencing texture updates in a video graphics system is accomplished by storing a first portion of graphics data in a first position of a bus master buffer, where the first portion of the graphics data utilizes a texture. An indication of a texture update is then received, where the texture update, when performed, modifies the texture to produce an updated texture that is used by subsequent graphics data. The updated texture is stored in a second position of the bus master buffer. A second portion of the graphics data, which utilizes the updated texture, is then stored in a third position of the bus master buffer. The data in the bus master buffer is then accessed through a direct memory access transfer initiated by the graphics processor in the system. The bus master buffer data is accessed in a sequential manner, which ensures that the texture update does not occur until after the graphics data utilizing the original texture has been drawn.
摘要翻译：通过将图形数据的第一部分存储在总线主缓冲器的第一位置中，其中图形数据的第一部分利用纹理来实现用于对视频图形系统中的纹理更新进行排序的方法和装置。然后接收纹理更新的指示，其中当执行纹理更新时，修改纹理以产生由后续图形数据使用的更新纹理。更新的纹理被存储在总线主缓冲器的第二位置。利用更新的纹理的图形数据的第二部分然后被存储在总线主缓冲器的第三位置。然后，总线主缓冲器中的数据通过由系统中的图形处理器发起的直接存储器访问传输来访问。以顺序方式访问总线主缓冲器数据，这确保了在绘制了利用原始纹理的图形数据之后才发生纹理更新。

摘要： An "eye-piece" system for an infra-red afocal telescope comprises a back element of positive power having a convex front surface and a curved back surface, and a pair of elements closely spaced to define a gas lens therebetween, the front element of the pair having a concave front surface whose radius of curvature is equal to or greater than that of the convex back surface of the back element of the pair, the pair of elements in combination with the gas lens therebetween being of positive power. The "eye-piece" system can be used in combination with an objective lens system, which may be catadioptric or all refractive, to provide a collimated magnified view of a scene or object, from which infra-red radiation is received, at a real exit pupil where a scanner operates.

摘要： A transfer lens comprises a first field-flattening component of negative power, a second component of positive power providing overcorrect astigmatism, a third component of positive power consisting of a plurality of positive members providing most of the power of the overall lens and whose undercorrect astigmatism is corrected by the overcorrect astigmatism of the second component, and a fourth component of negative power which increases the field angle. The lens is particularly useful in a head-down display having two primary displays from which light travels to a combiner so that the transfer lens produces a combined image. A Fresnel field lens is preferably located at the image position.
