astronomical image processing (aip) needs extremely interactive software systems. it is therefore necessary to execute in a short time frequently used, time consuming elaborations, such as convolution, geometrical normalization and geometrical correction. in the paper such operations have been split in a scalar part (typical of the operation) and in a vectorial part (in common among the whole operation set). in this way it is possible to achieve their optimization with regard to a native or attached vector processor. the common vectorial part (vectorial nucleus) is studied in detail and checked on vax 11/780+fps 5410, cray x-mp/12 and ibm 3090vf processors
