Open publisher page 0 citations

Abstract

An image acquisition and transmission system based on SOPC( System On Programmable Chip),which is a combination of hardware and software,is designed in this paper. Adopting SOPC technology,realize image acquisition,format conversion,and image cache on the FPGA,through the design of cache IP core based on DMA( Direct Memory Access),realize image data real-time accurate reading and transmission by Nios Ⅱ. The system proposed overcomes the previous cache image data in SDRAM is not visible for Nios Ⅱ,realizes reading the image data at any position accurately and effectively,is available to expand various software algorithms.
