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.
Certain AMD technologies may require third-party enablement or activation. Supported features may vary by operating system. Please confirm with system manufacturer for specific features. No technology or product can be completely secure.
