摘要： By mapping leaf nodes of a spatial index to processing elements, efficient distribution of workload in an image processing system may be achieved. In addition, processing elements may use a thread table to redistribute workload from processing elements which are experiencing an increased workload to processing elements which may be idle. Furthermore, the workload experienced by processing elements may be monitored in order to determine if workload is balanced. Periodically the leaf nodes for which processing elements are responsible may be remapped in response to a detected imbalance in workload. By monitoring the workload experienced by the processing elements and remapping leaf nodes to different processing elements in response to unbalanced workload, efficient distribution of workload may be maintained. Efficient distribution of workload may improve the performance of the image processing system.

摘要： Embodiments of the invention provide methods and systems to reduce the amount of space necessary to store a spatial index. According to embodiments of the invention, a spatial index may store pointers to information defining primitives which are located within bounding volumes defined by leaf nodes in the spatial index. The pointers may be smaller in size in contrast to information which defines the primitives, and the pointers may point to locations within a scene graph which contains information defining the primitives. Therefore, by storing pointers to primitives in the spatial index rather than the information which defines the primitives, the amount of space required to store the spatial index may be reduced.
摘要翻译：本发明的实施例提供了减少存储空间索引所需的空间量的方法和系统。根据本发明的实施例，空间索引可以存储指向位于由空间索引中的叶节点定义的边界卷内的基元的信息的指针。与定义基元的信息相反，指针的尺寸可能更小，并且指针可以指向场景图中包含定义基元的信息的位置。因此，通过在空间索引中存储指向基元的指针而不是定义基元的信息，可以减少存储空间索引所需的空间量。

摘要： Embodiments of the invention provide methods and apparatus for reallocating workload related to traversal of a ray through a spatial index. In a first operating state a workload manager may be experiencing a first or a normal workload. In the first operating state the workload manager may be responsible for traversing the entire spatial index and a vector throughput engine may be responsible for performing ray-primitive intersection tests. In an increased workload state the workload manager may experience an increased workload. In response to the increased workload the image processing system may partition the spatial index such that the workload manager may be responsible for traversing a first portion of the spatial index and the vector throughput engine may be responsible for traversing a second portion of the spatial index and for performing ray-primitive intersection tests.

摘要： The present invention is generally related to the field of image processing, and more specifically to an instruction set for processing images. Vector processing may involve performing a plurality of permute operations to arrange vector operands in desired locations of a register prior to performing vector operation, for example, a cross product. The permute instructions may be dependent on one another and may require the use of temporary registers. Embodiments of the invention provide a permute instruction wherein a mask field may be used to specify a particular location of a target register in which to transfer data, thereby reducing the number of instructions for arranging data, reducing dependencies between instructions, and the usage of temporary registers.

摘要： A method and circuit arrangement process a workload in a multithreaded processor that includes a plurality of hardware threads. Each thread receives at least one message carrying data to process the workload through a respective inbox from among a plurality of inboxes. A plurality of messages are received at a first inbox among the plurality of inboxes, wherein the first inbox is associated with a first thread among the plurality of hardware threads, and wherein each message is associated with a priority. From the plurality of received messages, a first message is selected to process in the first thread based on that first message being associated with the highest priority among the received messages. A second message is selected to process in the first thread based on that second message being associated with the earliest time stamp among the received messages and in response to processing the first message.

摘要： The present invention is generally related to the field of image processing, and more specifically to an instruction set for processing images. Vector processing may involve performing a plurality of dot product operations to generate operands for generating operands for a new vector. The dot product operations may require the issue of a plurality of permute instructions to arrange the vector operands in desired locations of a target register. Embodiments of the invention provide a dot product instruction wherein a mask field may be used to specify a particular location of a target register in which to transfer data, thereby avoiding the need for permute instructions for arranging data, reducing dependencies between instructions, and the usage of temporary registers.

摘要： According to one embodiment of the invention, by increasing the number of rays issued through adjacent pixels with colors of high contrast while maintaining the number of rays issued through adjacent pixels which do not have colors of high contrast, a ray tracing image processing system may render an anti-aliased image while minimizing the increase in workload experienced by the image processing system. Additionally, according to another embodiment of the invention, by maintaining the number of rays issued through adjacent pixels which have colors of low contrast while increasing the number of rays issued through adjacent pixels which do not have colors of low contrast, the image processing system may reduce workload experienced while performing ray tracing while maintaining the quality of the rendered image.
