Abstract: Among other things, one or more techniques and/or systems are disclosed for rendering a glyph. Rendering data for the glyph can be received, such as size, shape, color, etc., along with first sub-pixel position for initially rendering the glyph on a display. A first rendering quality can be identified for the first sub-pixel position and second rendering quality can be identified for a second sub-pixel position, which may comprise an alternate rendering position. A sub-pixel position shift can be selected for the glyph based at least upon a comparison of the first and second rendering qualities. The sub-pixel position shift can comprise a difference between the first sub-pixel position and the second sub-pixel position, where the second rendering quality is selected/preferable over the first rendering quality. The glyph can be rendered by applying the selected sub-pixel position shift.

Abstract: A method for dividing a display into zones at system initialization for tracking which zones have any pixels revised so that, when the time comes to update the display, only the zones requiring revision (that is, those zones in which any pixel has been revised) are copied from shadow memory to the frame buffer for display on the display device. The memory for tracking these zones can be allocated at initialization and held since it is relatively small. Consequently, a significant performance gain may be achieved by avoiding the shortcomings of the existing methods in the art notwithstanding the fact that some “clean” pixels in each zone having even a single changed pixel are also rewritten to the frame buffer.

Abstract: The method of one embodiment for the invention is for the CPU to read a subset of consecutive pixels from RAM and cache each such pixel in the WC Cache (and load corresponding blocks into the L2 Cache). These reads and loads continue until the capacity of the L2 Cache is reached, and then these blocks (a “band”) are iteratively processed until the entire band in the L2 Cache has been written to the frame buffer via the WC Cache. Once this is complete, the process then “dumps” the L2 Cache (that is, it ignores the existing blocks and allows them to be naturally pushed out with subsequent loads) and the next band of consecutive pixels is read (and their blocks loaded). This process continues until the portrait-oriented graphic is entirely loaded.
