摘要:
Video filtering using a programmable graphics processor is described. The programmable graphics processor may be programmed to complete a plurality of video filtering operations in a single pass through a fragment-processing pipeline within the programmable graphics processor. Video filtering functions such as deinterlacing, chroma up-sampling, scaling, and deblocking may be performed by the fragment-processing pipeline. The fragment-processing pipeline may be programmed to perform motion adaptive deinterlacing, wherein a spatially variant filter determines, on a pixel basis, whether a “bob”, a “blend”, or a “weave” operation should be used to process an interlaced image.

Circuits, methods, and apparatus that provide highly integrated digital media processors for digital consumer electronics applications. These digital media processors are capable of performing the parallel processing of multiple format audio, video, and graphics signals. In one embodiment, audio and video signals may be received from a variety of input devices or appliances, such as antennas, VCRs, DVDs, and networked devices such as camcorders and modems, while output audio and video signals may be provided to output devices such as televisions, monitors, and networked devices such as printers and networked video recorders. Another embodiment of the present invention interfaces with a variety of devices such as navigation, entertainment, safety, memory, and networking devices. This embodiment can also be configured for use in a digital TV, set-top box, or home server. In this configuration, video and audio streams may be received from a number of cable, satellite, Internet, and consumer devices.
摘要:
An integrated circuit includes at least two different types of processors, such as a graphics processor and a video processor. At least one operation is commonly by supported by two different types of processors. For each commonly supported operation that is scheduled, a decision is made to determine which type of processor will be selected to implement the operation.
摘要:
Parallelism in a parallel processing subsystem is exploited in a scalable manner. A problem to be solved can be hierarchically decomposed into at least two levels of sub-problems. Individual threads of program execution are defined to solve the lowest-level sub-problems. The threads are grouped into one or more thread arrays, each of which solves a higher-level sub-problem. The thread arrays are executable by processing cores, each of which can execute at least one thread array at a time. Thread arrays can be grouped into grids of independent thread arrays, which solve still higher-level sub-problems or an entire problem. Thread arrays within a grid, or entire grids, can be distributed across all of the available processing cores as available in a particular system implementation.
摘要:
Parallel data processing systems and methods use cooperative thread arrays (CTAs), i.e., groups of multiple threads that concurrently execute the same program on an input data set to produce an output data set. Each thread in a CTA has a unique identifier (thread ID) that can be assigned at thread launch time. The thread ID controls various aspects of the thread's processing behavior such as the portion of the input data set to be processed by each thread, the portion of an output data set to be produced by each thread, and/or sharing of intermediate results among threads. Mechanisms for loading and launching CTAs in a representative processing core and for synchronizing threads within a CTA are also described.
