The HLCDC IP provides a way to discard a specific area on the primary plane (in case at least one of the overlay is activated and alpha blending is disabled). Doing this will reduce the amount of data to transfer from the main memory to the Display Controller, and thus alleviate the load on the memory bus (since this link is quite limited on such hardware, this kind of optimization is really important).
