Description
Compressed Display Buffer Pitch. This value represents the number of QWORDs
between consecutive scan lines of compressed buffer data in memory. This pitch must
be set to a multiple of four QWORDs (i.e., bits [17:16] must be 00).
Frame Buffer Pitch. This value represents the number of QWORDs between consecu-
tive scan lines of frame buffer data in memory.
Description
Video U and V Buffer Pitch. This value represents the number of QWORDs between
consecutive scan lines of U or V buffer data in memory. (U and V video buffers are
always the same pitch.) A pitch up to 512 KB is supported to allow for vertical decimation
for downscaling.
Video Y Buffer Pitch. This value represents the number of QWORDs between consecu-
tive scan lines of Y buffer data in memory. A pitch up to 512 KB is supported to allow for
vertical decimation for downscaling.
