Data processing systems

A data processing system comprising:

• a display operable to display frames for display;
• a producer processing unit operable to generate frames for display on the display;
• a display processor operable to provide frames generated by the producer processing unit to the display for display, the display processor comprising a transformation engine operable to transform a frame generated by the producer processing unit based on a view orientation to provide a view orientation transformed frame for display on the display;
• wherein the transformation engine is configured to:
• for a frame generated by the producer processing unit to be displayed on the display that is to be transformed based on a predicted view orientation:
• for each of plural different regions of the frame:
• determine a predicted view orientation transformation matrix to use to transform the region of the frame by interpolating between a first predicted view orientation matrix that corresponds to a transformation for a predicted view orientation for a first time during the display of the frame and a second predicted view orientation matrix that corresponds to a predicted view orientation for a second, later time during the display of the frame;
• and
• use the interpolated predicted view orientation transformation matrix determined for the region of the frame to transform the region of the frame to provide an output predicted view orientation transformed version of the region of the frame;
• such that each different region of the frame is subjected to a different predicted view orientation transformation to the other regions of the frame for which an interpolated predicted view orientation matrix is determined.

A non-transitory computer readable storage medium storing computer software code that when executing on at least one processor performs a method of operating a data processing system, the data processing system comprising:

• a display operable to display frames for display;
• a producer processing unit operable to generate frames for display on the display;
• a display processor operable to provide frames generated by the producer processing unit to the display for display, the display processor comprising a transformation engine operable to transform a frame generated by the producer processing unit based on a view orientation to provide a view orientation transformed frame for display on the display;
• the method comprising:
• when displaying a frame generated by the producer processing unit that is to be transformed based on a predicted view orientation on the display:
• the transformation engine transforming the frame for display on the display by, for each of plural different regions of the frame:
• determining a predicted view orientation transformation matrix to use to transform the region of the frame by interpolating between a first predicted view orientation matrix that corresponds to a transformation for a predicted view orientation for a first time during the display of the frame and a second predicted view orientation matrix that corresponds to a predicted view orientation for a second, later time during the display of the frame;
• and
• using the interpolated predicted view orientation transformation matrix determined for the region of the frame to transform the region of the frame to provide an output predicted view orientation transformed version of the region of the frame;
• such that each different region of the frame is subjected to a different predicted view orientation transformation to the other regions of the frame for which an interpolated predicted view orientation matrix is determined.
