A data processing system comprises processing circuitry arranged to generate data to form an output array of data, processing circuitry arranged to store the generated data in an output bufferby writing compressed blocks of data representing particular regions of the output array of data to the output buffer, processing circuitryarranged to read a compressed block of data representing a particular region of the array of data from the output buffer, processing circuitryarranged to acquire meta-data from the compressed block of data, and processing circuitryarranged to process the block of data. The acquired meta-data is used to affect the processing of the block of data.

Data processing systems

A method and an apparatus are provided for generating an output frame from an input frame, in which the input frame is processed when generating the output frame. A region of a current input frame is compared with a region of a preceding input frame to determine if the region of the current input frame is similar to the region of the preceding input frame. When the region of the current input frame is determined to be similar to the region of the preceding input frame, information relating to processing performed on the region of the preceding input frame when generating a region of a preceding output frame is read, wherein the information is generated during the processing on the region of the preceding input frame. When the information indicates that the processing is unnecessary, a part or all of the processing of the region of the current input frame can be bypassed or eliminated.
