Due to processing of multi-channel two-dimension data, the realization of the image fusion algorithm makes a high requirement to the I/O and process capacities of the image fusion system. The high performance digital signal processor (DSP) combined with the parallel structure can provide the possibility for the realization of the real time image fusion. This paper introduces a parallel system composed by three high speed DSPs-- TMS320C6201, which can accomplish two-channel multi-spectrum image fusion real-time by pyramid algorithm at the pixel level. The system analyses the characters ofthe pyramid algorithm, and makes fully use ofthe hardware parallel structure and software pipeline. As a result, the system fairly balances heavy computation burden of some fusion algorithms, mass data storage and real-time request for hardware, which ensures the real-time realization of complex image fusion algorithm.
