Embedded Signal Processor for UUV Applications

Abstract : The objectives of the Unmanned Undersea Vehicle (UUV) program was to provide High Performance Scaleable Computing (HPSC) technology developed at Lockheed Martin in a scaleable 24 GFLOP HPSC processor for 21 inch UUV applications. The demonstration platform was to extend prior work that was done under Martin Labs (now integrated with Lockheed Sanders) for NUWC (the DAP system) by integrating HPSC technology to transform the DAP system into a real time embedded system suitable for UUVSP applications. It was decided that Naval Undersea Warfare Center (NUWC) would provide bottom-mapping algorithms for this demonstration. This algorithm was known as the Bathymetric Algorithm. This algorithm was provided to Sanders as a C program that ran on a UNIX workstation. Sanders was responsible for tailoring this algorithm into a scaleable process. The algorithm was tailored to use the Wideband Computers Inc. ADSP-21K Optimized DSP Library, and technology developed under the HPSC program for moving information between processing resources.
