An SoC System for the Image Grabber Capable of 2D Scanning

Abstract

This paper reports the implementation of an SoC (System on a Chip) IP(Intellectual Property) design for an Image Grabber that is capable of 2D scanning. The vast improvements in integrated circuit technology and semiconductor industry have allowed complicated hardware systems to be implemented into a single Chip. Previously, hardware designed by external buses was slow. However, the speed of the system has been improved by peripheral logics that are designed on a single chip. In addition, both hardware and software can be constructed together resulting in a significant decrease in research and development time. Four IPs were created in this study. I2C IP was developed for the Image Decoder. The NTSC analog signal from a CCD camera was converted to YUV422 using an image decoder and stored in a frame buffer by IMAGE IP. TFT-LCD IP was developed to display the data on an LCD. A robot IP was developed to control a perpendicular coordinate robot. Finally, system level software and PC software was developed to examine the SoC system.
