Abstract: A process of updating data for a block of an array of data elements stored in an allocated memory region for the block comprises reading in data for a first group of the data elements, updating the data for the first group, and then writing back the updated data to memory. The process can avoid overwriting data for a second group of the data elements that is yet to be read in from the memory region by writing back the updated data for the first group starting at a selected memory address, for example other than the start address of the memory region. The data for the second group of data elements can then be read in and updated, and the updated data can be written back to memory. The process can reduce the amount of memory bandwidth and local cache that needs to be used.

Abstract: In a graphics processing system, a driver for the graphics processing pipeline can include conditional graphics processing tasks in the graphics processing tasks that are to be executed by the graphics processing pipeline to generate a render output required by an application. Each such conditional task has associated with it a condition to be used by the graphics processing pipeline to determine whether to execute processing for the task or not and a region of the render output over which the processing for the task will be executed when the condition for the task is met. The graphics processing pipeline determines whether the condition associated with the task has been met, and only executes the processing for the task if the condition associated with the task has been met.

Abstract: An image processing apparatus and method including an encoder circuitry for generating encoded data blocks from input data blocks of an image, and write circuitry for storing the encoded data blocks to memory for subsequent access by decoding circuitry. For each input data block, identifier generation circuitry generates an identifier value that is dependent on the input data block. A lookup storage stores predetermined information relating to at least one encoded data block and stored within the lookup storage in association with the identifier value for the corresponding input data block. For a current input data block, a check is performed to determine whether a match exists between the identifier value generated for the current input data block and an identifier value stored in the lookup storage. In a match, the predetermined information is used by the write circuitry when performing the required write operation.
