摘要
利用SOPC双核技术开发了高速数据采集系统,采用无缝缓存技术和双核并行处理技术,实现对高速CCD相机下发的图像数据的采集存储,并通过FPGA内部的SOPC主控制器将存储的图像数据通过Ft245上传到上位机,经M atlab还原该数据得到的图像与原下发图像一致,具有较好的实用性。
Basing on the dual-core SOPC,a high-speed data acquisition system(DAS) was designed to capture the images from the CCD camera by making use of the seamless cache and dual-cored parallel processing,and then have them transferred to master computer via Ft245.Comparing the images restored with the originals proves the practicability of this design.
