| Abstract: | This paper introduces an independent multi-resolution VGA/DVI image compression and storage system.This system can receive graphics signal from both DVI and VGA interface,support multi-resolution compression including SVGA,XGA,SXGA,UXGA and 1080p,and can implement compression and storage continuously.When the system works at 100 MHz,the compression frame rate of the system can achieve 25 and 17 frames/s to SXGA and UXGA respectively.The experimental result shows that this system has similar performance comp... |
