Abstract: A graphics processing unit (GPU) adjusts a frequency of clock based on identifying a program thread executing at the processing unit, wherein the program thread is detected based on a workload to be executed. By adjusting the clock frequency based on the identified program thread, the processing unit adapts to different processing demands of different program threads. Further, by identifying the program thread based on workload, the processing unit adapts the clock frequency based on processing demands, thereby conserving processing resources.

Abstract: An apparatus, such as a head mounted device (HMD), includes one or more processors configured to implement a graphics pipeline that renders pixels in window space with a nonuniform pixel spacing. The apparatus also includes a first distortion function that maps the non-uniformly spaced pixels in window space to uniformly spaced pixels in raster space. The apparatus further includes a scan converter configured to sample the pixels in window space through the first distortion function. The scan converter is configured to render display pixels used to generate an image for display to a user based on the uniformly spaced pixels in raster space. In some cases, the pixels in the window space are rendered such that a pixel density per subtended area is constant across the user's field of view.

CPC classification number: G06T15/005
Abstract: A system, method and a computer program product are provided for hybrid rendering with deferred primitive batch binning. A primitive batch is generated from a sequence of primitives. Initial bin intercepts are identified for primitives in the primitive batch. A bin for processing is identified. The bin corresponds to a region of a screen space. Pixels of the primitives intercepting the identified bin are processed. Next bin intercepts are identified while the primitives intercepting the identified bin are processed.

Abstract: A multi-die parallel processor semiconductor package includes a first base IC die including a first plurality of virtual compute dies 3D stacked on top of the first base IC die. A first subset of a parallel processing pipeline logic is positioned at the first plurality of virtual compute dies. Additionally, a second subset of the parallel processing pipeline logic is positioned at the first base IC die. The multi-die parallel processor semiconductor package also includes a second base IC die including a second plurality of virtual compute dies 3D stacked on top of the second base IC die. An active bridge chip communicably couples a first interconnect structure of the first base IC die to a first interconnect structure of the second base IC die.

Abstract: A graphics processing unit (GPU) or other apparatus includes a plurality of shader engines. The apparatus also includes a first front end (FE) circuit and one or more second FE circuits. The first FE circuit is configured to schedule geometry workloads for the plurality of shader engines in a first mode. The first FE circuit is configured to schedule geometry workloads for a first subset of the plurality of shader engines and the one or more second FE circuits are configured to schedule geometry workloads for a second subset of the plurality of shader engines in a second mode. In some cases, a partition switch is configured to selectively connect the first FE circuit or the one or more second FE circuits to the second subset of the plurality of shader engines depending on whether the apparatus is in the first mode or the second mode.

Abstract: An apparatus such as a graphics processing unit (GPU) includes a plurality of processing elements configured to concurrently execute a plurality of first waves and accumulators associated with the plurality of processing elements. The accumulators are configured to store accumulated values representative of behavioral characteristics of the plurality of first waves that are concurrently executing on the plurality of processing elements. The apparatus also includes a dispatcher configured to dispatch second waves to the plurality of processing elements based on comparisons of values representative of behavioral characteristics of the second waves and the accumulated values stored in the accumulators. In some cases, the behavioral characteristics of the plurality of first waves comprise at least one of fetch bandwidths, usage of an arithmetic logic unit (ALU), and number of export operations.

Abstract: A graphics processing unit (GPU) includes a plurality of programmable processing cores configured to process graphics primitives and corresponding data and a plurality of fixed-function hardware units. The plurality of processing cores and the plurality of fixed-function hardware units are configured to implement a configurable number of virtual pipelines to concurrently process different command flows. Each virtual pipeline includes a configurable number of fragments and an operational state of each virtual pipeline is specified by a different context. The configurable number of virtual pipelines can be modified from a first number to a second number that is different than the first number. An emulation of a fixed-function hardware unit can be instantiated on one or more of the graphics processing cores in response to detection of a bottleneck in a fixed-function hardware unit. One or more of the virtual pipelines can then be reconfigured to utilize the emulation instead of the fixed-function hardware unit.

Abstract: A first workload is executed in a first subset of pipelines of a processing unit. A second workload is executed in a second subset of the pipelines of the processing unit. The second workload is dependent upon the first workload. The first and second workloads are suspended and state information for the first and second workloads is stored in a first memory in response to suspending the first and second workloads. In some cases, a third workload executes in a third subset of the pipelines of the processing unit concurrently with executing the first and second workloads. In some cases, a fourth workload is executed in the first and second pipelines after suspending the first and second workloads. The first and second pipelines are resumed on the basis of the stored state information in response to completion or suspension of the fourth workload.

Abstract: An array processor includes processor element arrays distributed in rows and columns. The processor element arrays perform operations on parameter values. The array processor also includes memory interfaces that are dynamically mapped to mutually exclusive subsets of the rows and columns of the processor element arrays based on dimensions of matrices that provide the parameter values to the processor element arrays. In some cases, the processor element arrays are vector arithmetic logic unit (ALU) processors and the memory interfaces are direct memory access (DMA) engines. The rows of the processor element arrays in the subsets are mutually exclusive to the rows in the other subsets and the columns of the processor element arrays in the subsets are mutually exclusive to the columns in the other subsets. The matrices can be symmetric or asymmetric, e.g., one of the matrices can be a vector having a single column.

Abstract: The address of the draw or dispatch packet responsible for creating an exception is tied to a shader/wavefront back to the draw command from which it originated. In various embodiments, a method of operating a graphics pipeline and exception handling includes receiving, at a command processor of a graphics processing unit (GPU), an exception signal indicating an occurrence of a pipeline exception at a shader stage of a graphics pipeline. The shader stage generates an exception signal in response to a pipeline exception and transmits the exception signal to the command processor. The command processor determines, based on the exception signal, an address of a command packet responsible for the occurrence of the pipeline exception.
