Abstract: This paper introduces a new method based on system on programmable chip(SOPC) technology and dual NiosII processor to design VoD system with 16 terminals. It provides a technique about how to apply the “Ping-pong” theory to achieve high speed data transfer, and how to communicate synchronously between two CPUs.
