Abstract: A method of operating a data processing system is disclosed for a data processing system that comprises a display and a display controller. The method comprises the display controller providing to the display data for an output surface to be displayed, storing the data in a memory of the display, and the display reading the data from the memory and displaying the output surface. The method further comprises the display controller indicating to the display a particular memory address of the memory, and the display using the indication to control the reading of data from the memory. The display controller may provide to the display image data for one or more sub-regions of the output surface that were not present in a previous version of the output surface.

Abstract: A method of operating a data processing system 4 is disclosed that comprises producing data in the form of blocks of data, where each block of data represents a particular region of a data array, processing the data using a processing operation in which one or more output data values are each determined using data values from plural different lines of the data array, storing the processed data in a memory 21 of the data processing system, and reading the data from the memory 21 in the form of lines.

Abstract: An interface apparatus and method of operating the same are provided. The interface apparatus receives an uncompressed image data read request using a first addressing scheme at a first bus interface and transmits a compressed image data read request using a second addressing scheme from a second bus interface. Address translation circuitry translates between the first addressing scheme and the second addressing scheme. Decoding circuitry decodes a set of compressed image data received via the second bus interface to generate the set of uncompressed image data which is then transmitted via the first bus interface. The use of a second addressing scheme and image data compression is thus transparent to the source of the uncompressed image data read request, and the interface apparatus can therefore be used to connect devices which use different addressing schemes and image data formats, without either needing to be modified.
