LogiCORE IP Video Scaler, Software Driver v4.02.a - Why does the Video Scaler stop accepting input video if the input, output, and aperture are 2048 or larger and using the Video Scaler software driver?

描述

Why does the Video Scaler stop accepting input video if the input, output, and aperture are 2048 or larger and using the Video Scaler software driver?

解决方案

The problem is that the software driver MASKS off the incorrect bits which results in the wrong value being written to the input, output, or aperture registers.
