Description

The Video Stream Scaler scales streaming video up or down in resolution. Bilinear and nearest neighbor resize
modes are supported.

This core provides run-time adjustment of input and output resolution, scaling factors, and scale
type. Compile time adjustment of maximum resolutions and data width.
