摘要： A vectorizable execution unit is capable of being operated in a plurality of modes, with the processing lanes in the vectorizable execution unit grouped into different combinations of logical execution units in different modes. By doing so, processing lanes can be selectively grouped together to operate as different types of vector execution units and/or scalar execution units, and if desired, dynamically switched during runtime to process various types of instruction streams in a manner that is best suited for each type of instruction stream. As a consequence, a single vectorizable execution unit may be configurable, e.g., via software control, to operate either as a vector execution or a plurality of scalar execution units.

摘要： Embodiments of the invention are generally related to image processing, and more specifically to vector units for supporting image processing. A combined vector/scalar unit is provided wherein one or more processing lanes of the vector unit are used for performing scalar operations. An integrated register file is also provided for storing vector and scalar data. Therefore, the transfer of data to memory to exchange data between independent vector and scalar units is obviated and a significant amount of chip area is saved.

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.

摘要： According to embodiments of the invention, a distributed time base signal may be coupled to a memory directory which provides address translation for data located within a memory cache. The memory directory may have attribute bits which indicate whether or not the memory entries have been accessed by the distributed time base signal. Furthermore, the memory directory may have attribute bits which indicate whether or not a memory directory entry should be considered invalid after an access to the memory entry by the distributed time base signal. If the memory directory entry has been accessed by the distributed time base signal and the memory directory entry should be considered invalid after the access by the time base signal, any attempted address translation using the memory directory entry may cause a cache miss. The cache miss may initiate the retrieval of valid data from memory.
摘要翻译：根据本发明的实施例，分布式时基信号可以耦合到为位于存储器高速缓存内的数据提供地址转换的存储器目录。存储器目录可以具有指示存储器条目是否已经被分布式时基信号访问的属性位。此外，存储器目录可以具有指示在通过分布式时基信号访问存储器条目之后存储目录条目是否应被视为无效的属性位。如果通过分布式时基信号访问存储器目录条目，并且在通过时基信号访问之后，存储器目录条目应被视为无效，则使用存储器目录条目的任何尝试的地址转换可能导致高速缓存未命中。高速缓存未命中可以启动从存储器检索有效数据。

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： The present invention is generally related to integrated circuit devices, and more particularly, to methods, systems and design structures for 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： The present invention is generally related to the field of image processing, and more specifically to vector units for supporting image processing. A dual vector unit implementation is described wherein two vector units are configured receive data from a common register file. The vector units may independently and simultaneously process instructions. Furthermore, the vector units may be adapted to perform scalar operations thereby integrating the vector and scalar processing. The vector units may also be configured to share resources to perform an operation, for example, a cross product operation.

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： A circuit arrangement and method utilize texture data prefetching to prefetch texture data used by an anisotropic filtering algorithm. In particular, stride-based prefetching may be used to prefetch texture data for use in anisotropic filtering, where the value of the stride, or difference between successive accesses, is based upon a distance in a memory address space between sample points taken along the line of anisotropy used in an anisotropic filtering algorithm.
