Abstract: Arbitrary size texture palettes. A texture palette storage embodied in a computer readable medium is provided. The texture palette storage is partitioned into texture palette tables of arbitrary size. Texel data is stored for each of the texture palette tables in the texture palette storage. Another aspect is a palette memory that receives a texture index value of y-bits. The palette memory comprises subtables of different length. Each sub-table has a range with a start address and a length. The start address is a multiple of m. Each range is of a length addressable by y-bits. The palette memory also includes a sub-table index value of x-bits.

Abstract: Processing pixels in a graphics pipeline. Screen coincidence between a first pixel and a second pixel in a graphics pipeline is detected, wherein the first pixel has entered a downstream pipeline portion of the graphics pipeline but has not yet completed processing within the graphics pipeline. In response to detecting the coincidence, propagation of the second pixel to the downstream pipeline portion is stalled until the first pixel completes processing within the graphics pipeline. A data cache associated with the data fetch stage is invalidated in advance of a data fetch stage of the downstream pipeline portion obtaining data for the second pixel.
