可编程片上系统(SOPC)是Altera公司提出的一种灵活、高效的片上系统解决方案,为构建实时、小型化的红外图像处理器提供了有效的解决途径.介绍了一种基于SOPC技术的红外图像处理器,可对数字红外图像进行实时处理和显示驱动.处理器主要包括非均匀校正模块、实时图像增强模块和显示驱动模块.处理功能主要由一片Altera公司的SOPC芯片EPXA4完成.实验结果表明,采用SOPC技术构建的红外图像处理器集成度高、功耗低、可靠性强、实时性好.

SOPC is a flexible and efficient SOC design methodology which is developed by Altera Corporation. Small efficient infrared image processor can be developed with the technology advantage of SOPC. In the paper, an infrared image processor based on SOPC technology is discussed, which has realtime infrared image processing and display driving function. The processor mainly encompasses a nonuniformity correction module, a real-time image enhancement module and a display driver. A single SOPC chip EPXA4 of Altera Corporation implements the main function of the processor. Experimental results show that the infrared image processor based on SOPC has high real-time performance,small bulk and low power dissipation.
