Video Processing IP Cores

ACC Innovations offers real-time video processing IP cores for image/video processing and pre-processing algorithms as well as more complex vision-based embedded applications. The functionality of the offered IP Cores was evaluated on the Atlys 2 FPGA Board using real-time data acquisition from HDMI cameras, and our cores are also synthesizable across multiple technologies (PLDs, ASICs).

RGB to YUV Color Space Converter

General Description:

This IP core converts digital RGB signals used in computer graphics to luminance and color difference coded signals (YUV), which is used by many component video systems.

Key Design Features:

• Convert three input color samples to three output samples in a single clock cycle 

Applications:

• Image Transmission
• Image Compression

On-Chip Video Frame Buffer

General Description:

The on-chip video frame buffer core provides the ability to store the input camera stream to an on-chip memory for fast local processing. The on-chip frame buffer is useful for applications where it is necessary to access pixels at different image locations which is not concurrent with the camera stream.

Key Design Features:

• Capture video frame from camera stream synchronized with the pixel clock.
• Ability to pause/resume frame grabbing until processing the captured frame.

Applications:

• Multi-resolution Image Processing
• Image Capture/Storing
