In video processing systems, AXI4-Stream is used to transmit video frames between video decoders, image processors, and display units. The VGA output ensures the processed video is displayed correctly on a monitor or screen.
Detailed Explanation
In video processing applications, there is a need to move video frames rapidly between different components like decoders and processors. AXI4-Stream makes this possible by transmitting data in a continuous flow, which is crucial for maintaining video quality. The VGA output is then utilized to display these processed frames properly on screens, ensuring the visuals are clear and fluid.
Examples & Analogies
Imagine you are creating a movie. You have actors (video decoders), a director (image processor), and a screen (VGA output). Just like how the director needs to ensure that scenes transition smoothly for the audience, AXI4-Stream ensures that video frames are sent accurately and continuously to the display, thus making the viewing experience enjoyable.
