High-speed TMS320C6416DSP as the core processing unit, developed a new generation of high-speed infrared real-time imaging system. In order to improve the performance of the system and ensure the integrity of the image data, a new method of data transmission using ring caching mechanism and data transfer using DMA mechanism based on message mechanism was proposed. The system is innovative, reliable, and can meet the system’s real-time performance requirements. The composition and implementation of the system are described in detail. Finally, the real-time performance of the system is analyzed and the experimental results are given.
