基于SOPC技术的高速图像采集控制系统的设计与研究
Design and Research of a High-Speed Image Acquisition System Based on SOPC Technology
摘要
Abstract
Based on SOPC (System on a Programmable Chip) technology, some peripherals embedded in Avalon bus were customized and utilized in image acquisition unit, compression unit and storage unit, and these measures improved the speed of the whole imaging system. The data is compressed to three-fourths of the original. A custom DMA is designed for transferring the image data to the two caches of the SDRAM. This approach discards the method that FIFO must be put up in the traditional data acquisition system. And therefore, it reduced the CPU task for data transferring. At the same time, the image acquisition and the data transmission can complete a parallel job to improve the system efficiency. Finally,the design is worked on an 2kx2k high-speed CMOS image system,and the test results show its feasibility and flexibility in high-speed image acquisition applications.关键词
