摘要
以高速TMS320C6416DSP为核心处理单元,研制了新一代的高速红外实时成像系统。为提高系统的性能,保证图像数据的完整性,提出了用环形缓存机制存储数据、采用基于消息机制的DMA方式进行数据传输的新方法。该系统方案新颖、工作可靠、能够很好地满足系统实时性能的要求。对系统的构成及实现原理进行了详细阐述。最后分析了系统的实时性能并给出了实验结果。
A new IR imaging system is developed based on TMS320C6416. In order to improve the performance of the system and to ensure the integrality of image data, a new method which uses circular buffer mechanism to store data and DMA manner to transfer data based on message mechanism is presented. The scheme is novel and reliable,and meets the demands of the real-time performance of system well. The architecture and system theory are described in detail. Finally,the real-time performance of the system is analyzed and experiental results are shown and discussed.
