Abstract: A raster operations (ROP) unit is configured to compress stencil values included in a stencil buffer. The ROP unit divides the stencil values into groups, subdivides each group into two halves, and selects an anchor value for each half. If the difference between each of the stencil values and the corresponding anchor lies within an offset range, and the difference between the two anchors lies within a delta range, then the group is compressible. For a compressible group, the ROP unit encodes the anchor value, offsets from anchors, and an anchor delta. This encoding enables the ROP unit to operate on the compressed group instead of the uncompressed stencil values, reducing the number of memory and computational operations associated with the stencil values. Consequently, the ROP unit reduces memory bandwidth use, reduces power consumption, and increases rendering rate compared to conventional ROP units that implement less flexible compression techniques.

Abstract: A method and apparatus for controlling sparse refresh of a self-refreshing display device coupled to a graphics controller are disclosed. The display device includes capabilities to drive the display based on video signals generated from a local frame buffer. The graphics controller may optimally be placed in one or more power-saving states when the display device is operating in a panel self-refresh mode. When exiting the power-saving state to update the image displayed by the display device, a fast-resume initialization routine may be run to reconfigure the GPU when operating in a sparse refresh mode, i.e., where the image being displayed on the display device is updated infrequently. In such cases, the graphics controller may be configured to receive instructions and data from a central processing unit via an alternative low-bandwidth communications path instead of the high-bandwidth communications path used in normal operation.
