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/military imaging.
The VIP Suite features cores that range from simple color space conversion to sophisticated video scaling functions that can implement programmable polyphase scaling. Table 1 lists some of the cores included in the VIP Suite.
- All the VIP cores use a open, low-overhead interface standard (Avalon® 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 the Quartus®II software or from within MATLAB/Simulink tools.
- 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 arbitration logic.

| IP MegaCore Function |
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, as well as 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 |
| Peripheral IP |
Converts a clocked video format (BT-656) to Avalon ST Video and vice versa |
Note:
-
Complete VIP Suite includes additional cores.
