Abstract :
We have successfully designed the low power single chip MPEG1 codec LSI which is the most suitable for portable devices such as digital cameras. By adopting compact and efficient motion estimation process and embedding SDRAM for storing image data inside, this chip realizes compactness and low power of the system
