| Abstract: | Based on the need for real-time image gathering in embedded system, this paper designs a Multi-resolution image gathering and processing system based on CPLD and DSP devices. This paper put forwards a method that vertical and horizontal signal delayed, odd and even data separately stored are controlled by CPLD so that different resolution images are generated. This paper also introduces logic functional design of data gathering; design of logic bus switching and CPLD software realization etc. in detail. |
