摘要： A phototherapy system and device is disclosed, including an array of light sources arranged so as to achieve substantially uniform distribution of light on a subject. The light sources can be arranged in a number of configurations, including but not limited to distributions in which the density of lights sources is greater in the periphery than in the center. The present invention also includes a light diffusing panel to increase exposure uniformity, and a targeting mechanism to ensure that the device is properly aligned over the subject.

摘要： A programmable graphics pipeline and method for processing multiple partitioned multimedia data, such as graphics data, image data, video data, or audio data. A preferred embodiment of the programmable graphics pipeline includes an instruction cache, a register file, and a vector functional unit that perform partitioned instructions. In addition, an enhanced rasterization unit is used to generate inverse-mapped source coordinates in addition to destination output coordinates for graphics and other media processing. An enhanced texture address unit generates corresponding memory addresses of source texture data for graphics processing and source media data for media processing. Data retrieved from memory are stored in an enhanced texture cache for use by the vector functional unit. A vector output unit includes a blending unit for graphics data and an output buffer for wide media data.

摘要： A boundary macroblock of a video object is padded without significant synchronization overhead between a host processor and an existing coprocessor. The host processor determines horizontal and vertical graphics primitives as a function of shape data stored in a host memory. The shape data determine whether a dot, a line, or a rectangle primitive should be used to pad transparent pixels in the macroblock. The host processor communicates the primitives to a coprocessor, which renders the primitives in an interleaved pipeline fashion to pad transparent pixels of the macroblock based on texture data stored in video memory. The flow of primitives is in one direction from the host processor to the graphics coprocessor, and the texture data is not transferred back and forth between the host processor and coprocessor. This technique is especially useful for enabling acceleration of MPEG-4 video decoding utilizing existing coprocessors capable of accelerating MPEG-1/2 video decoding.
