4.3 LINT Parameters
The phase of the rst output pixel is programmed using PCoeff (reg
0x10,E2A8[21:16]). The upscaling ratio is programmed in DPCoeff (reg
0x10,E2A8[11:0]).
Table 13 shows the min-max values of the LINT programming
parameters.
If Scaling ratio == 1
DPCoeff = 0
// the decimal bits for 1.0000_0000_0000
else
DPCoeff = (1000 * H) / Scaling ratio
4.4 HSRU Parameters
The phase of the rst output pixel is programmed via HSRU_phase (reg 0x10
E2AC[5:0]). HSRU_d_phase (reg 0x10E2AC[27:16]) is the rst-order phase
difference of the rst output pixel, while HSRU_dd_phase (reg 0x10 E2B0[11:0]) and
HSRU_ddd_phase (reg 0x10 E2B0[25:16]) are the second and the third-order phase
differences, respectively, of the rst output pixel.
Table 14 shows the min-max values
of the programmable HSRU parameters. Note that the decimal points are actually
aligned for the different values and “s: stands of the sign extension that is
automatically performed by hardware (only the lower
non-s values need to be
programmed).
For bypassing the HSRU, all the control parameters have to be set to 0.
