10:0 AUX_YWS[10:0]
R/W 0
Vertical auxiliary window start
The line cosited with the reference edge REVS is numbered 0.
Offset 0x10 6184
Auxiliary Acquisition Window End
31:27 reserved
-
26:16 AUX_XWE[10:0]
R/W 0
Horizontal auxiliary window end
pixels from XWS up to and including XWE are processed
15:11 reserved
-
10:0 AUX_YWE[10:0]
R/W 0
Vertical auxiliary window end
lines from YWS up to and including YWE are processed
Horizontal Video Processing Control Registers
Offset 0x10 6200
Initial Zoom
31:29 HSP_PHASE_MODE[2: R/W 0
0]
Phase mode
0: 64 phases
1: 32 phases
2: 16 phases
3: 8 phases
4: 4 phases
5: 2 phases
6: fixed phase
7: linear phase interpolation (only valid for4 component mode)
28:27 reserved
-
26 HSP_FIR_COMP[1:0] R/W
Horizontal filter components
0: three components, 6 tap FIR each
1: four components, 3 tap FIR each (4th component unused)
In color space matrix mode this value has to remain zero
25:20 reserved
19: 0 HSP_ZOOM_0[19:0]
-
R/W 0
Initial zoom for 1st pixel in line (unsigned, LSB = 2^-16)
2 0000 (hex): downscale 50%
1 0000 (hex): no scaling = 2 ⁰
0 8000 (hex): zoom 2 x (transposed: downscale 50%)
Offset 0x10 6204
Phase Control
31 reserved
-
30:28 HSP_QSHIFT[2:0]
R/W 0
Quantization shift control
used to change quantization before being multiplied with
HSP_MULTIPLY.
100 (bin): divide by 16
101 (bin): divide by 8
110 (bin): divide by 4
111 (bin): divide by 2
000 (bin): multiply by 1
001 (bin): multiply by 2
010 (bin): multiply by 4
011 (bin): multiply by 8
Warning: A value range overflow caused by an improper
quantization shift can not be compensated later by multiplying with a
HSP_MULTIPLY value below 0.5!
