Abstract
PROCESSING REQUIREMENTS FOR NEXT GENERATION SONAR SYSTEMS WILL REQUIRE THE USE OF THE AN/UYS-2. THIS NEW GENERATION STANDARD SIGNAL PROCESSOR IS A PARALLEL DISTRIBUTED PROCESSING SYSTEM THAT IS BASED ON ASTATE-OF-THE-ART DATA FLOW METHODOLOGY USING NEW LANGUAGES SUCH AS ADA, THE PROCESSING GRAPH METHOD SIGNAL PROCESSING GRAPH NOTATION (PGM/SPGN), AND THE PRIMITIVE INTERFACE DEFINITION (PID) LANGUAGE. CURRENT SONAR SIGNAL PROCESSING APPLICATIONS ARE PROGRAMMED FOR THE AN/UYS-1, USING SPL/I AND SPL ASSEMBLY LANGUAGE. EVOLVING SOF TWARE METHODOLOGIES HAVE BEEN EMPLOYED DURING THE LIFE CYCLE OF THE AN/UYS-1; EACHMETHODOLOGY WILL HAVE ITS OWN UNIQUE ISSUES ASSOCIATED WITH MIGRATION TO THE AN/UYS-2. PROGRAMMING AN APPLICATION ON THE AN/UYS-1 AND THE AN/UYS-2 IS SIMILAR IN SOME FUNDAMENTAL WAYS, BUT THERE ARE MANY SIGNIFICANT DIFFERENCES. SOME OF THE MAJOR DIFFERENCES BETWEEN APPLICATIONS DEVELOPED FOR THE AN/UYS-1 AND THOSE DEVELOPED FOR THE AN/UYS-2INCLUDE: - PROGRAMMING LANGUAGES ARE DIFFERENT. - NO ONE-TO-ONE MAPPING BETWEEN COMPUTER SOFTWARE CONFIGURATION ITEMS (CSCI) EXISTS. - EACH ARCHITECTURE HAS ADAPTED A DIFFERENT RUN-TIME SUPPORT METHODOLOGY WHICH IMPACTS EVENT SCHEDULING, DATA MANAGEMENT AND MULTIPLE CHANNEL PROCESSING. - FIXED POINT VERSUS FLOATING POINT HARDWARE IMPLEMENTATIONS. - OPERATIONAL DIFFERENCES INCLUDE STATIC VERSUS DYNAMICRECONFIGURATION CAPABILITY. THIS EFFORT WILL FOCUS ON TECHNIQUES AND COMPUTER-ASSISTED IMPLEMENTATION OF THESE TECHNIQUES WHICH ARE NEEDED TO EXPEDITE THE MIGRATION OF EXISTING (FUNCTIONALLY CORRECT) APPLICATION SOFTWARE FROM THE AN/UYS-1 TO THE AN/UYS-2 ENVIRONMENT. WITHOUT SUCH TECHNIQUES AND TOOLS, THE TRANSITION WILL BE COSTLY AND TIME CONSUMING.
