As shown, there is one set of registers for the video data capture engine, and this set is shared between
both pipelines at register locations MR02-MR1A -- i.e., this one set of registers is accessible at register
locations MR02-MR1A in both shadows of the MR register set.
Where the playback engines are concerned, technically speaking, the registers for each of them are shared
between the two pipes, but they are not shared at the same register locations across both pipelines -- they
are “cross-shared” as mentioned earlier to allow both video playback engines to be accessible through the
shadow belonging to either pipe. The registers of video playback engine 1 are accessible at MR1E-MR42
of pipeline A’s shadow of the MR register set and at MR9E-MRC2 of pipeline B’s shadow. Taking the
reverse of video playback engine 1, the registers of video playback engine 2 are accessible at MR9E-MRC2
of pipeline A’s shadow, and at MR1E-MR42 of pipeline B’s shadow.
In either dual-pipe simultaneous mode or dual-pipe mosaic mode where each pipe is making use of a video
playback engine, it is presumed that pipeline A would be using playback engine 1 through its shadow of
register locations MR1E-MR42, while pipeline B would be using playback engine 2 through its shadow of
the same register locations.
In dual-pipe mosaic mode or the single-pipe modes where one pipe, pipeline A for example, were making
use of both video playback engines, playback engine 1 would be used through pipeline A’s shadow of
register locations MR1E-MR42, and playback engine 2 would be used through pipeline A’s shadow of
register locations MR9E-MRC2.
