A multifunctional signal processing system for unmanned underwater vehicles

This paper focuses on the design of a multifunctional signal processing system for unmanned underwater vehicles. It takes the multicore DSP TMS320C6678 as the primary processor. The design of two most important parts of the system, processing board and master board, are given in detail. The system uses CPCI as power supply channel and data bus, SRIO and gigabyte ethernet are provided for data transmitting. Finally, a test is run on the system to prove it satisfies the demand of most underwater signal processing missions.
