摘要： Methods and apparatus for utilizing coefficient compression in graphics decoding are provided. In one example, a computer processing unit (CPU) is interfaced with a graphic processing unit (GPU) where the CPU extracts coefficients and passes compressed coefficient data, preferably in uniformly sized data packets, to the GPU for decoding and coefficient processing. Preferably the extracted coefficients are inverse transform (iT) coefficients and CPU includes an encoder control component configured to adaptively select a coefficient encoding process for performing the iT coefficient data compression based on the data content of the iT coefficients such that data packets are generated that include data that indentifies the selected coefficient encoding process used for encoding the compressed iT coefficient data contained in the data packet. In such case, the GPU is configured to receive such data packets and decode the iT coefficient data within each packet using a coefficient decoding method complementary to the selected coefficient encoding process identified within the packet. The GPU preferably uses massively parallel coefficient decoding of such data packets.

摘要： Apparatus, computer readable medium, and method of allocating media resources, the method including determining a media resources allocation table based on one or more media hardware resources and predetermined benchmarks of media hardware resources for performing media operations; in response to receiving a request for media resources from a first application, comparing the requested media resources with the media resources allocation table; and if the comparison indicates that the requested media resources are available, then allocating the requested media resources to the first application in the media resources allocation table, and sending a response to the request for media resources to the first application indicating the requested media resources are allocated to the application. If the comparison indicates that the requested media resources are not available, then sending indicating to the first application that the requested media resources are not allocated to the first application.

摘要： A image processing system for displaying a source image includes a memory for storing a source image having a high resolution digital format, a display screen having a low resolution digital format, and a media acceleration hardware unit adapted to increase color depth values from the source image and generate a plurality of temporally shifted images from the source image by sequentially shifting an origin point for a frame applied to the source image and scaling source image pixel values from each frame, thereby generating the plurality of shifted images having the second, relatively low resolution for display at the display screen.

摘要： Systems, methods, and media for providing libraries within an OpenCL framework. Library source code is compiled into an intermediate representation and distributed to an end-user computing system. The computing system typically includes a CPU and one or more GPUs. The CPU compiles the intermediate representation of the library into an executable binary targeted to run on the GPUs. The CPU executes a host application, which invokes a kernel from the binary. The CPU retrieves the kernel from the binary and conveys the kernel to a GPU for execution.
