摘要： Multiple aggregation groups, which can be multiple partitions in an aggregated data table, are formed. Each group includes multiple aggregation records; each aggregation record includes an aggregation of values contained by a different subset of multiple database records. While an aggregation group is accessed by a single program thread during an aggregation group update transaction, no other threads are allowed to access that group. The aggregation groups are combined into a single table of aggregation records. Each of the multiple database records may correspond to an instance of an organizational activity and include a field having a value indicating the corresponding instance to be in one of several process states. Each aggregation group may further include time-sorted aggregation records, each time-sorted aggregation record containing an aggregation value for instances in one of the several process states during a time period associated with the time-sorted aggregation record. Aggregation records corresponding to instances completed outside of a preselected time window are deleted.

摘要： A multi-threaded processor is provided that internally reorders output threads thereby avoiding the need for an external output reorder buffer. The multi-threaded processor writes its thread results back to an internal memory buffer to guarantee that thread results are outputted in the same order in which the threads are received. A thread scheduler within the multi-threaded processor manages thread ordering control to avoid the need for an external reorder buffer. A compiler for the multi-threaded processor converts instructions that would normally send processed results directly to an external reorder buffer so that the processed thread results are instead sent to the internal memory buffer of the multi-threaded processor.

摘要： A multi-threaded processor is provided, such as a shader processor, having an internal unified memory space that is shared by a plurality of threads and is dynamically assigned to threads as needed. A mapping table that maps virtual registers to available internal addresses in the unified memory space so that thread registers can be stored in contiguous or non-contiguous memory addresses. Dynamic sizing of the virtual registers allows flexible allocation of the unified memory space depending on the type and size of data in a thread register. Yet another feature provides an efficient method for storing graphics data in the unified memory space to improve fetch and store operations from the memory space. In particular, pixel data for four pixels in a thread are stored across four memory devices having independent input/output ports that permit the four pixels to be read in a single clock cycle for processing.

摘要： A 3D graphics pipeline includes a prefetch mechanism that feeds a cache of depth tiles. The prefetch mechanism may be predictive, using triangle geometry information from previous pipeline stages to pre-charge the cache, thereby allowing for an increase in memory bandwidth efficiency. A z-value compression technique may be optionally utilized to allow for a further reduction in power consumption and memory bandwidth.

摘要： Configuration information is used to make a determination to bypass fragment shading by a shader unit of a graphics processing unit, the shader unit capable of performing both vertex shading and fragment shader. Based on the determination, the shader unit performs vertex shading and bypasses fragment shading. A processing element other than the shader unit, such as a pixel blender, can be used to perform some fragment shading. Power is managed to “turn off” power to unused components in a case that fragment shading is bypassed. For example, power can be turned off to a number of arithmetic logic units, the shader unit using the reduced number of arithmetic logic unit to perform vertex shading. At least one register bank of the shader unit can be used as a FIFO buffer storing pixel attribute data for use, with texture data, to fragment shading operations by another processing element.

摘要： A graphics processing unit (GPU) efficiently performs 3-dimensional (3-D) clipping using processing units used for other graphics functions. The GPU includes first and second hardware units and at least one buffer. The first hardware unit performs 3-D clipping of primitives using a first processing unit used for a first graphics function, e.g., an ALU used for triangle setup, depth gradient setup, etc. The first hardware unit may perform 3-D clipping by (a) computing clip codes for each vertex of each primitive, (b) determining whether to pass, discard or clip each primitive based on the clip codes for all vertices of the primitive, and (c) clipping each primitive to be clipped against clipping planes. The second hardware unit computes attribute component values for new vertices resulting from the 3-D clipping, e.g., using an ALU used for attribute gradient setup, attribute interpolation, etc. The buffer(s) store intermediate results of the 3-D clipping.
