基于FPGA的低功耗微型图像采集系统的设计

Design of Low-power Miniature Image Acquisition System Based on FPGA

为了满足项目应用的需求,设计了一个基于FPGA的低功耗微型图像采集系统。结合CMOS图像探测器的特点,选用Microsemi公司的FPGA作为硬件设计平台,使用Verilog-HDL硬件描述语言进行描述,并采用自上而下的模块化设计思想对整个系统进行设计。实验结果表明,所设计的图像采集系统在1280*1024分辨率、20f/s的情况下可以实时稳定的实现图像的显示与存储,图像质量良好。

In order to meet the needs of project application,this paper designs a low power miniature image acquisition system based on FPGA.The system combines the characteristics of CMOS image detectors,and Field Programmable Gate Array（FPGA） of Microsemi is chosen as the hardware design platform,with Verilog-HDL to perform the modularization design from top to bottom.Experimental results show that real-time 1280＊1024 resolution high quality image display and storage could be achieved at speed 20f/s.
