The Video Frame Buffer IP Core buffers video data in external memory to be displayed on output devices such as computer monitors, projectors, and others. The Video Frame Buffer IP Core supports image sizes up to 4K x 4K with YCbCr 4:2:2, 4:4:4 and RGB video formats. It supports dynamic parameter updating through a parameter bus, which can be configured to operate on a different clock from the core. Simple frame rate conversion is employed to support different input and output frame rates.

Features

  • Supports single color, YCbCr 4:2:2, YcbCr 4:4:4 and RGB video formats
  • Supports input and output resolutions of 64 × 64 to 4k × 4k pixels
  • Supports serial and parallel pixel processing
  • Supports frame rate conversion
  • Supports dynamic parameter update of frame size and Keep mode
