This paper presents the first VLSI implementation of a real-time color video compression/ decompression system, based on the threedimensional discrete cosine transform (3D-DCT).Compared to motion-estimation/compensation based algorithms, the 3D-DCT approach has three major advantages:• No motion estimation is required, greatly reducing the number of en/decoding operations per pixel.• En-and Decoder are symmetric with almost identical structure and complexity, which facilitates their joint implementation.• The complexity of the implementation is independent of the compression ratio.These factors are key issues for the realization of mobile video compression systems.We describe the system architecture and implementation.Tradeoffs that facilitate the VLSI implementation are emphasized and performance results are presented.
