Current we are using the resizer module to convert yuv422 to yuv420, but we do not known the difference between resizer's pass by mode and pass thought mode? We have read the manual about resizer module.the RSZ_GCK_SDR register record the folowing words:
RSZ Core Clock Enable. RW 0
This bit enables or disables the resizer core functional
clock. When this bit is off, the resizer core (interpolator) is
automatically bypassed (resizer-bypass mode of
pass-through mode is selected depending on
RSZ_SRC_FMT0 value). In resizer-bypass mode or
pass-through mode, no up-scaling or downscaling
process is operated.
0x0: Resizer core clock disabled.
Resizer in bypass mode if RSZ_SRC_FMT0.BYPASS = 0
Resizer in pass-through if RSZ_SRC_FMT0.BYPASS = 1
0x1: Resizer core clock enabled.
Resizer in rescaling mode if RSZ_SRC_FMT0.BYPASS =
0
Resizer in pass-through if RSZ_SRC_FMT0.BYPASS = 1
We can not understand . How to set the resizer which don't recale size and only convert yuv422 to yuv420?
Can you help me ?
