Customizable Video Input Controller with color space conversion

Overview

CVI is a fully Customizable Video Input controller IP core. The video input controller can be applied to e.g. FPGA systems with a resource optimized, application specific feature configuration or to ASIC projects applying a more generic feature set and thus more flexibility.

Key Features

Configurable Input Formats
Configurable Output Formats
Configurable Codeword Correction
Configurable Chroma-Upsampling to YCBCR444
Configurable Clipping Area
Configurable Color Adjustment
Configurable Colorspace Conversion: precise conversion between YCBCR and RGB
Configurable Gamma Correction
Configurable Scaling
Configurable Deinterlacing
Configurable Dithering
Configurable Counter
Frame Detection
Configurable Shadowing (shadow registers)

Benefits

The main functionality of CVI is reading an ITU-656 video input stream typically coming from a physical video input interface, e.g. a LVDS PHY or a video ADC, and writing the video data in RGB format to memory via DMA. Several on-the-fly operations on the video data can be applied such as clipping, scaling, color conversion, gamma correction, dithering and de-interlacing.
On the input side CVI can accept RGB as well as YCbCr color formats, in the latter case applying the on-the-fly conversion YCbCr to RGB.

Applications
