基于FPGA的多DSP红外实时图像处理系统

Multi-DSP Processing System of Real-time Infrared Image Based on FPGA

多处理器系统已广泛应用于高速信号处理领域,为提高系统性能,更好地发挥多处理器优势,介绍采用基于FPGA的多DSP架构。利用FPGA作为数据调度核心,将处理器从繁杂的数据通信工作中解放出来,充分发挥了多处理器的并行工作能力,增强了系统的重构和拓展性。该系统已应用于工程实践中,以一块高密度电路板实现了从数据采集到图像校正、图像处理,以及图像显示的整个流程,能够满足对处理时间要求较高、较为复杂的图像处理算法的要求。

Multi processor systems have been widely applied in high-speed signal processing field. In order to improve the system performance and better to use the multiple processors, the advantages of digital architecture based on FPGA are intro- duced. The FPGA is used as data processor core, and the processor is dispatched from multifarious data communication, the concurrent ability of multi-processors is fully used, the reconstruction and expansion of the system are strengthened. This system has been applied in engineering practice, the entire process of the data acquisition, image revise image processing and image display are achieved with a high density board achieved. It can satisfy the requirement of complex image processing algorithm.
