Product Description

The Chroma Resampler LogiCORE IP converts video data between commonly used chroma formats.

The Chroma Resampler core converts between chroma formats of 4:4:4, 4:2:2, and 4:2:0. There are six conversions available for the three supported formats. Conversion is achieved using a FIR filter approach. Some conversions require filtering in only the horizontal dimension, vertical dimension, or both.  Interpolation operations are implemented using a two-phase polyphase FIR filter.  Decimation operations are implemented using a low-pass FIR filter to suppress chroma aliasing.
