Zhu Jing

Abstract

In this paper,a design scheme of embedded digital video image acquisition module on SoPC technology is introduced.By configuring Nios Ⅱ soft core CPU,I2C configuration module of ADV181,video image acquisition module,video image decoding and color scheme transformation module and some related corresponding interfaces module on a Cyclone Ⅱ FPGA,the hardware platform of the system is constructed,and design software of integrated development environment Nios Ⅱ IDE of Altera Company is applied to control the whole data acquiring process.The module realizes A/D conversion,data saving and displaying of digital video image.
