Figure 9-109 is the top-level block diagram of the CNF module. The RSZ module comprises the following submodules: cropping, input data buffering, data requestor, averager, data saturation, and resizer interpolation (comprised of horizontal rescaler, vertical rescaler, color conversion, and output interface) (see the following sections for more information).
Figure 9-109 ISS ISP CNF Top Level Block DiagramAlthough CNF does not generate horizontal blanking violation error interrupts. This is because CDS module will always generate enough blanking. Instead, inadequate number of horizontal blanking cycles will eventually generate back pressure to RSZ1 input buffer, and will cause buffer over flow if the upstream receiver module can not be stalled.
