基于SOPC的红外图像采集系统

Infrared Image Acquisition Based on SOPC

介绍了一种基于SOPC的红外线列图像采集系统。在一片FPGA中嵌入了MicroBlaze微处理器和用户逻辑,实现了CPU和FPGA的优势互补,发挥了CPU在控制、通信等方面的优势和FPGA在时序控制、高速传输、并行计算的优势,较好地完成线列探测器的驱动、采样、模数转换、传输等功能,实现了红外图像采集。

This paper introduces an infrared linear arrays image acquire system based on SOPC（system on programmable chip）. The system realizes completmentary strengths of both CPU and FPGA by using MicroBlaze and user logical in a single FPGA chip. It makes full use of not only CPU advantages in control and communication fields, but also FPGA＇s in timing control, high-speed transmission, and parallel computing. This system completes following functions very well including driving, sampling, analog-digital conversion, and transmission, to carry out infrared image acquisition.
