Torpedo signal processor

A torpedo sonar signal processor comprising:

• a plurality of low-pass, delta-sigma based sixteen-bit analog-to-digital converters, arrayed in groups, and receiving input from a pre-amplifier of a sonar array;
• a plurality of field programmable gate array 10K gates each attached to and receiving input from the sixteen-bit analog-to-digital converters in a single group;
• a plurality of first digital signal processors having only internal memory, each attached to and receiving input from one of said plurality of field programmable gate arrays;
• a plurality of second dual-port digital signal processors having only internal memory, each second digital signal processor attached to and receiving input from a pair of said first digital signal processors;
• a beamformer comprising a single dual-port digital signal processor having both an internal and a first external memory and attached to said plurality of second digital signal processors;
• a signal processor attached to and receiving input from said beamformer, said signal processor comprising four dual-port digital signal processors arranged in parallel, each of said digital signal processors having an internal memory and sharing a common second external memory;
• and
• a network controller comprising a single dual port digital signal processor attached to and providing two-way data flow through said signal processor.
