MVout_f0 (Motion vectors)
In the previously listed ports, except Y and UV (current) and Scalar output (current) (referred to as main
data), all the other ports directly interact with DEI through VPDMA and are referred to as auxiliary data for
DEI module. All the Y and UV ports in auxiliary data require 8 bits/pixel while MV port requires 4 bits/pixel.
1.2.9.2.4.1 4-field MDT-based Interpolation Mode
In this mode, the required external memories are three fields of Luma input, three fields of chroma input,
and two fields of 4-bit MV.
