6.5.3.3.6 Multi-Source Blending

Up to eight sources are supported. Programmable block size guarantees cache efficiency, so each source is read once and the blended destination is written once. 90, 180, 270 degree destination and source rotations are supported and mirror with different block size to have high cache efficiency.

Different source rectangles are supported with independent source stretch/shrink with blending and rotation. Up to four video inputs can be multi-sourced.
