Abstract
A layer selection module for a graphics display component, and method therefor. The layer selection module is arranged to identify a set M of active layers to be blended for a pixel, configure a display controller to generate composite pixel data for the pixel based on a subset N of up to n layers from the set M, determine whether a number m of active layers in the set M exceeds n, and output an indication of which active layers within the set M were excluded from the subset N, if it is determined that the number m of layers in the set M exceeds n.
Claims22
A processing system comprising:
- a processing unit;
- a layer selection module for a graphics display component, the layer selection module being arranged to, for at least one pixel to be displayed:
- identify a set M of active layers for the at least one pixel;
- configure a display controller to generate composite pixel data for the at least one pixel based on a subset N of up to n layers from the set M;
- determine whether a number m of active layers in the set M exceeds n;
- and
- output to the processing unit an indication of which active layers within the set M were excluded from the subset N, if it is determined that the number m of layers in the set M exceeds n;
- a graphics management component executed by the processing unit and arranged to receive the indication that active layers within the set M were excluded from the subset N, and to cause a number k of graphics layers within a set K from which the composite image as a whole is generated to be reduced to form a reduced set K′.

A method of managing graphics layers within a graphics display component, the method comprising, within a layer selection module:
- identifying a set M of active layers for the at least one pixel;
- configuring a display controller to generate composite pixel data for the at least one pixel based on a subset N of up to n layers from the set M;
- determining whether a number m of active layers in the set M exceeds n;
- and
- if it is determined that the number m of layers in the set M exceeds n:
- outputting to a processor an indication of which active layers within the set M were excluded from the subset N and;
- generating a composite image based on a number k of graphics layers within a set K from which the composite image as a whole is generated to be reduced to form a reduced set K′.
