TYPE
Y (vertical) scaler Accumulation (calculation) Mode of vertical
arithmetic:
Y scaler increment for vertical downscaling:
accumulation sequence Length of the Y (vertical) processing:
vertical start phase for vertical scaling of the ODD field:
vertical start phase for vertical scaling of the EVEN field:
reserved
0: arithmetic operates as a linear phase interpolation (LPI)
1: arithmetic operates as accumulating FIR filter in vertical
direction.
YSCI = INT [1024
YSCI = INT [1024
YACM = 1
N
N
Defines vertical accumulation sequence length of input lines
If accumulation FIR filter mode is selected YACM, YACL has to
fit to the vertical scaling factor (defined by YSCI)
YPO = PHOL
(PHOL represents a phase offset with values between logic 0
and logic 1, where the logic 1 represents a distance between two
consecutive lines of the input pattern)
YPE = PHOL
(PHOL represents a phase offset with values between logic 0
and logic 1, where the logic 1 represents a distance between two
consecutive lines of the input pattern).
