摘　　要：基于ZYNQ-7000片上系统(SOC)的嵌入式图像处理模块实现了特征点提取和高速数据传输,降低了图像处理部分的功耗,同时提高了处理速度。为了同时发挥ZYNQ芯片中处理器系统(PS)和可编程逻辑(PL)的优势,在PL中实现计算密集型的图像处理过程以提高处理速度,而在PS中控制系统的流程以提高模块的灵活性,还利用Vivado HLS高层次综合工具生成特征提取和坐标计算的IP核。所提出的图像处理和传输方案具有较高的处理速度,比基于ARM的方案实现速度提升了15.6倍。Feature point extraction and high-speed data transmission is realized based on embedded image processing module of ZYNQ-7000 system-on-a-chip(SOC),which reduces the power consumption of the image processing part and improves the processing speed.In order to simultaneously take advantage of the processor system(PS)and programmable logic(PL)in the ZYNQ chip,increase the processing speed,a computationally intensive image processing process is implemented in the PL.The flow of the system is controlled in the PS to improve the module.flexibility.IP cores for feature extraction and coordinate calculations are also generated using the Vivado HLS high-level synthesis tool.The proposed image processing and transmission scheme has a higher processing speed and is 15.6 times faster than the ARM-based scheme.
