Scaler takes in a 10-bit YCbCr 422 video frame from an upstream module, performs vertical/horizontal scaling and outputs a YCbCr422 scaled image to a next downstream module. All configurations are done via the MMR interface except for the scaler coefficient memory configuration that is done via the common VPI control interface bus by VPDMA. Figure 10-18 shows the high-level block diagram of the scaler module.
The SC is used in the video path and in all other video write-back data paths in the VPE module.
Scaling is performed in following three steps:
