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.

Key Features

  • Supports conversion between YCbCr 4:4:4, 4:2:2, and 4:2:0
  • Image edges padded to eliminate edge artifacts
  • Supports Progressive or Interlaced Video
  • Programmable clipping and clamping of output results
  • Three resampling options allow resource utilization trade-off
  • Supports 8, 10 and 12-bits per color component input and output
  • Supports spatial resolutions from 32x32 up to 7680x7680
    • Supports 1080P60 in all supported device families
    • Supports 4kx2k @ 24 Hz in supported high performance devices
