The overlay manager (OVR) is responsible for compositing selected input layers together to generate the final display output frame. The DISPC implements four identical overlay managers, one for each display output (see Figure 12-311, DISPC Architecture Overview). Any of these overlay managers can be used to source also the Write-back pipeline.
Each OVR is preceded by a programmable input pipeline selector which re-maps the output of the selected input pipelines according to the overlay manager Z-order configuration.
The DISPC overlay managers, OVR1 through OVR4, will be commonly refered to as overlay manager (OVR) in the following sections.
