摘　　要：为解决红外系统图像数据传输的瓶颈问题,提高动态显示的稳定性和连续性,提出了用DMA重组传输数据,用多线程技术动态显示图像的新方法。在介绍了以PC机和TMS320C6201 DSP信号处理板构成的实时红外系统原理的基础上,阐述了DMA重组传输数据的实现过程以及多线程技术动态显示图像的原理及程序实现。实验结果表明,上述技术是可行的、有效的,能够显著提高系统的实时性,系统可达到理想的实时动态显示效果。To solve the bottleneck problem of image data transmission in infrared system and improve stability and eontinuity of dynamie display, a new method using DMA data transmission and multi-thread teehnique displaying image is presented. The prineiple of real-time infrared system based on PC and TMS320C6201 DSP board is introdueed firstly. Then, realization of DMA rearrangement data transmission and multi-thread teehnique are depieted. Experi- mental results show that teehniques above-mentioned are feasible and effieient. They can signifieantly improve the real-time performanee of system. Ideal real-time dynamie display effeets ean be obtained in the system.
