Altera's Video and Image Processing Suite MegaCore Functions
from Altera Corporation
Features and Description
The Altera® Video and Image Processing (VIP) Suite is a collection of MegaCore® functions that you can use to facilitate the development of custom video and image processing designs. These MegaCore functions are suitable for use in a wide variety of image processing and display applications, such as video surveillance, broadcast, video conferencing, and medical and military imaging.
The VIP Suite features cores that range from simple building block functions such as color space conversion to sophisticated video scaling functions that can implement programmable polyphase scaling. Table 1 lists all the cores included in the VIP Suite.
- All the VIP cores use an open, low-overhead interface standard (Avalon® Streaming (ST) Video) so that they can be connected together easily.
- You can use VIP cores to quickly build a custom video processing signal chain using Quartus® II software or SOPC Builder.
- You can mix-and-match VIP cores with your own proprietary intellectual property (IP).
- You can use SOPC Builder to automatically integrate embedded processors and generate arbitration logic.

Description |
| Color Space Converter |
Converts image data between a variety of different color spaces such as RGB to YCrCb. |
| Chroma Resampler |
Changes the sampling rate of the chroma data for image frames, for example from 4:2:2 to 4:4:4 or 4:2:2 to 4:2:0. |
| 2D FIR Filter |
Implements a 3 x 3, 5 x 5, or 7 x 7 finite impulse response (FIR) filter on an image data stream to smooth or sharpen images. |
| Alpha Blending Mixer |
Mixes and blends multiple image streams—useful for implementing text overlay and picture-in-picture mixing. |
| Scaler |
A sophisticated polyphase scaler that allows custom scaling and real-time updates of both the image sizes and the scaling coefficients. |
| Deinterlacer |
Converts interlaced video formats to progressive video format using a motion adaptive deinterlacing algorithm. |
| Line Buffer Compiler |
Efficiently maps video line buffers to Altera on-chip memories. |
| Clipper |
Provides a way to clip video streams and can be configured at compile time or at run time. |
| Color Plane Sequencer |
Changes how color plane samples are transmitted across the Avalon-ST interface. This function can be used to split and join video streams, giving control over the routing of color plane samples. |
| Frame Buffer |
Buffers video frames into external RAM. This core supports double or triple-buffering with a range of options for frame dropping and repeating. |
| 2D Median Filter |
Provides a way to apply 3 x 3, 5 x 5, or 7 x 7 pixel median filters to video images. |
| Gamma Corrector |
Allows video streams to be corrected for the physical properties of display devices. |
| Clocked Video Input/Output |
Converts a clocked video format (BT-656) to Avalon-ST video and vice versa. |
