Pipeline architecture of specialized reconfigurable processors in FPGA structures for real-time image pre-processing

The article presents considerations concerning the choice of a multiprocessor unit architecture for fast realization of the tasks connected with initial processing of visual images. Based on the earlier experience of the author within the scope of real time systems, implementation in pipeline architecture of specialized hardware processor-assembled on the basis of FPGA programmable structures-was suggested. In particular, implementation of the following processor has been prepared: median filtration, convolution, look-up-table recording, logic processor, histogram count-up and morphological processors. Experimental work has also been done, in order to verify the concept assumed, whose results associated with delay times are included in the article. A structure of universal reconfigurable processor has been moreover offered. The works have been financed by the Polish Scientific Research Committee.
