摘要： This disclosure is directed toward systems and methods of pre-multiplied alpha handling during image processing operations. The image processing circuitry may include hardware that enables removal and insertion of pre-multiplied alpha content into red, green, blue (RGB) pixel values during gamma and scaling operations. The division by alpha and multiplication by alpha hardware may enable removal of pre-multiplied alpha content to RGB pixel values prior to gamma operations and insertion of pre-multiplied alpha content into RGB pixel values prior to scaling operations.

摘要： A method of modifying a font character. An outline of the font character is received, the outline being a vector representation of the character. A slant angle parameter to be applied to the font outline is received, the slant angle specifying an amount of shearing to be applied to the font outline. A modified stroke width is determined for each segment of the font outline according to an initial angle of the segment and the slant angle, the modified stroke width being proportional to ratio of a length of the segment before and after applying the slant angle to the outline. The modified stroke width is used for adjusting an initial stroke width of the segment to compensate for changes to stroke width of the segment caused by applying the slant angle. The font character is rendered using the modified stroke width of the segments.

摘要： Systems, methods, and computer-readable media are disclosed for dynamic contrast adjustment for glyph rendering. Example methods may include rendering a first glyph associated with a font in a first font size, increasing a first contrast of the first glyph in the first font size by adjusting a first grayscale value associated with the first glyph in the first font size to generate an adjusted first grayscale value, and storing the adjusted first grayscale value in a grayscale mapping table associated with the font, the grayscale mapping table comprising a default grayscale value for the first glyph in a second font size. Example methods may include generating a font file comprising the first glyph and the grayscale mapping table.

摘要： A graphics display system integrated circuit is used in a set-top box for controlling a television display. The graphics display system processes analog video input, digital video input, and graphics input. The system incorporates a unified memory architecture that is shared by the graphics system, a CPU, and other peripherals. The unified memory architecture uses real time scheduling to service tasks. Critical instant analysis is used to find a schedule for memory usage that does not affect memory requirements of real time tasks while at the same time servicing non-real-time tasks as needed.

摘要： Disclosed herein are various embodiments of a graphics accelerator, which may include an integrated circuit. The integrated circuit may include a local memory; a direct memory access (DMA) engine; a processor; and one or more processing pipelines. The local memory stores graphics data that includes a plurality of pixels. The DMA engine transfers the graphics data between the local memory and an external memory. The processor performs at least one operation, in parallel, on components of at least a portion of the pixels. The one or more processing pipelines process the graphics data. The graphics accelerator works on operands and produces outputs for one set of pixels while the DMA engine is bringing in operands for a future set of pixel operations, and transfers data from the external memory to the one or more processing pipelines by directing data to the one or more pipelines.
