Color Space Converters (CSC) convert signals from one color space to another color space. Color space conversion is often required to ensure compatibility with display devices or to make the image data amenable for compression or transmission. CSCs are widely used in video and image display systems including televisions, computer monitors, color printers, video telephony and surveillance systems. They are also used in many video/image compression and processing applications, and in the implementation of NTSC/PAL/SECAM television standards, JPEG and MPEG systems.

The Lattice Color Space Converter IP Core is widely parameterizable and can support any custom color space conversion requirement. Furthermore, several commonly used color space conversion methods are provided as readyto-use configurations.

Features

  • Input and Output data width from 8 to 16 bits
  • Signed or unsigned input and output data
  • Supports standard configurations as well as custom configurations
  • Parameterized coefficients precision from 9 to 18 bits
  • Optional sequential or parallel architecture for area or throughput optimization

Avant (LAV-AT-500E-3LFG1156I)
Configuration Clk Fmax (MHz)1 Registers LUTs DSP
Default 179.99 MHz 344 190 9
Architecture = Sequential,
Others = Default		 251.76 251 73 3
Core Type = YUV to Computer RGB,
