Abstract: In order to solve real-time performance of large field, high resolution optoelectronic processing system, this paper analyzes the characteristic of task of detecting optoelectronic small weak targets and the primary principle of design of real-time parallel processor through three factors such as processor nodes, memory and the network connecting the processor nodes. It puts forward a parallel processor consists of double DSP + FPGA based on SRIO technology. The low level algorithm is realized with FPGA and the high level algorithm is realized by DSPs. A region-decomposing parallel algorithm which is fit for digital image processing is adopted for dividing image-processing task. Experimental result shows the feasibility of the design.
