Abstract: Image data is subject to compression and decompression when it is respectively written to and read from a frame buffer. If a portion of the image data is identified as static (subject to less than a threshold amount of change for greater than a threshold time), then compression control parameters used for compression of that portion of the image are adjusted so as to increase the compression ratio achieved, hold the degree of lossiness substantially constant and increase the energy consumed while compressing that portion. The increased energy consumption during this high compression ratio compression is likely compensated for by a reduction in energy subsequently consumed when writing that frame-buffer image data to the frame buffer and reading that frame-buffer image data multiple times from the frame buffer. The compression characteristics varied may be to increase the block size used in the compression. Other variations in compression applied may be to change from single-pass compression to multi-pass compression, switch compression on and off altogether, or reorder the data when it has been compressed so as to match the order it will be read and so achieve support for longer read burst.

Abstract: A graphics processing apparatus and method of graphics processing is disclosed. Obscuration identification circuitry is configured to receive graphics fragments from rasterization circuitry and to identify an obscuration condition if a received graphics fragment, in combination with at least one previously received graphics fragment, will obscure at least one further previously received graphics fragment. Process killing circuitry is configured to prevent further processing occurring in the graphics processing apparatus with respect to the at least one further previously received graphics fragment if the obscuration identification circuitry identifies the obscuration condition.

Abstract: An apparatus for processing data 2 is provided including processing circuitry 24 controlled by an instruction decoder 20 in response to a stream of program instructions. There is also provided dedicated function hardware 12 configured to receive output data from the processing circuitry and to perform a dedicated processing operation. The instruction decoder 20 is responsive to an end instruction 54 and a software processing flag (blend_shade_enabled) to control the processing circuitry to end a current software routine, to generate output data and in dependence upon the software processing flag either trigger processing of the output data by the dedicated function hardware or trigger the processing circuitry to perform a further software routine upon the output data to generate software generated result data instead of hardware generated result data as generated by the dedicated hardware circuitry.
