提出了一种基于NiosⅡ软核处理器的图像数据缓存系统的设计方案,设计中选用了FPGA+图像采集芯片+MosⅡ软核处理器+存储器的方案来实现系统功能,并对系统软硬件设计以及各功能模块的具体实现原理进行了讨论和分析,针对系统实现的功能进行了实际测试,测试结果验证了本设计的可行性、可靠性、通用性。
A design of image data cache system based on Nios Ⅱ soficore processor is presented in this paper. The FPGA, the image acquisition chip, the Nios Ⅱ softcore processor, together with the memory constitute the designed system to realize the prospective function. The system design of software and hardware are discussed and analyzed in detail, as well as the principle of each specific function module. In view of the functional realization of the system, the operational test is done. From the testing result, the feasibility, reliability, generality of the designed system presented in this paper are verified.
