摘要： According to one embodiment, an occurrence of an instruction is fetched. The instruction's format specifies its only source operand from a single vector write mask register, and specifies as its destination a single general purpose register. In addition, the instruction's format includes a first field whose contents selects the single vector write mask register, and includes a second field whose contents selects the single general purpose register. The source operand is a write mask including a plurality of one bit vector write mask elements that correspond to different multi-bit data element positions within architectural vector registers. The method also includes, responsive to executing the single occurrence of the single instruction, storing data in the single general purpose register such that its contents represent either a first or second scalar constant based on whether the plurality of one bit vector write mask elements in the source operand are all zero.

摘要： Hybrid sampling of pixels of an image involves generating shading values at multiple shading sample locations and generating depth values at multiple depth sample locations, with the number of depth sample locations exceeding the number of shading sample locations. Each shading sample location is associated with one or more of the depth sample locations. Generation and filtering of hybrid sampled pixel data can be done within a graphics processing system, transparent to an application that provides image data.

摘要： A graphics processor performed gamma correction of the coverage values of pixels. In one embodiment, a gamma correction factor is written into a run-time loadable lookup table of the graphics processor. The gamma corrected coverage values may be used in an anti-aliasing process to form smoothed primitives.

摘要： A method and system for efficient usage of revision control system resources by providing a client-based file system tree based on managed cache resources is provided. The managed cache resources include both a persistent, disk-based cache that maintains copies of requested file data from a repository server and an ordered tree data structure-based metadata cache for tracking file metadata across revisions. Embodiments of the present invention further maintain in the data cache data related only to specifically requested files. Embodiments of the present invention further track a range of versions of the file system tree for which particular file versions are applicable, so that unnecessary downloading to the client of unchanged files is avoided. Thus, file data and metadata are only requested from a repository server when needed and only a single version of a file is maintained until a modification to that file is made.

摘要： A graphics processing subsystem defines a bounding area as the portion of the display buffer and other memory buffers occupied by one or more rendered objects. When clearing the memory buffers, only the portions of the buffers corresponding to the bounding area need to be cleared. A graphics pipeline includes a bounding area memory to store bounding area values. The bounding area values are modified during rendering so that each rendered primitive falls within the bounding area values. The graphics processing subsystem clears a portion of the memory buffer in response to a clear command specifying a bounding area. The clear command may include a set of bounding area values defining the bounding area, or alternatively a reference to the bounding area memory. For applications that draw objects in isolation, the bounding area will be smaller than the window, resulting in a decreased time requirement for clearing the memory buffer.

摘要： Transferring data between a requesting program and a hardware device. An program requests a pre-allocation of non-pageable memory. The program requests a transfer via a direct memory access (DMA) from the hardware device into the non-pageable memory. The requesting program is notified when the DMA is complete. The requesting program reads the data from the non-pageable memory. A determination may be made whether a range of addresses specified in the DMA request is within the pre-allocated range of non-pageable memory. If the range of addresses is within the pre-allocated non-pageable memory, the data transfer involves fewer transfers between system memory and the CPU than if the range of addresses is outside the pre-allocated non-pageable memory.
摘要翻译： 在请求程序和硬件设备之间传送数据。 程序请求预分配不可分页内存。 该程序请求通过直接存储器访问（DMA）从硬件设备传输到非可页面存储器。 当DMA完成时通知请求程序。 请求程序从非可页面存储器读取数据。 可以确定DMA请求中指定的地址范围是否在非可分页存储器的预分配范围内。 如果地址范围在预先分配的非可浏览存储器内，则数据传输涉及在系统存储器和CPU之间的传输量较之如果地址范围在预先分配的非可浏览存储器之外。
