The screen timing generator setup should be performed first since this is usually
fixed for the target display. Once the screen timing is set up the screen timing
generator should still stay disabled until all other settings are complete.
In a second step the resource assignment for a particular display scenario should
be set up. This involves two sub-steps:
–
0
P
I
Each functional unit, whether it is located inside a layer or in the resource pool,
should be assigned to an aperture slot in the overall QVCP aperture.
