Abstract : This invention aims to provide a torpedo signal processor having an integrated analog to digital conversion with the digital signal processor. This invention also aims to provide a torpedo signal processor having a reduced number of components including external memory and reduced line drivers and receivers. It also provides a torpedo signal processor having reduced power requirements, reduced cooling requirements, reduced weight and reduced size. In accordance with these and other objects, the invention is an integrated torpedo signal processor having four groups of multiple low pass filtered analog to digital convertors, each group providing an input to a field programmable gate array and each field programmable gate array providing an input to a digital signal processor (DSP). Thereafter, the architecture provides output from pairs of the DSP's to a second level of DSP's for the prefiltering function.
