Color Space Converter with parallel interface


Overview

The CSC is an IP core, designed for color space conversion, based on 3 color channels with parallel interface. Its configurable structure allows to convert any color space to another, using standard equations.

Key Features
  • Configurable equations used for color space conversion

  • Predefined coefficients for standard conversions for RGB, SDTV, HDTV, PAL and NTSC in both direction

  • Configurable width of coefficients and summands

  • Configurable width of data input and output

  • Configurable data types for input and output

  • Guard values for input and output

  • Three integer rounding modes

  • Parallel interface
  • Synchronous with one clock domain, without latches

  • Parametrized source code prevents wasting silicon for unused functionality

  • Synchronous RTL design, implementable in every technology.

  • Test benches

Applications
  • Image processing
  • Image storing
  • Video data conversion
