Abstract
A modern signal processing algorithm has been widely used in the sonar system, which has improved the sonar system features, but has also given the sonar signal processing system more compute burden in the meantime. Parallel signal processing technology is a solution. A universal parallel signal processing module is designed, which is based on the VME bus, so it is convenient to get a more powerful processing system. This module is comprised of four TMS320C40 digital signal processors. As examples, some basic sonar signal processing algorithms such as FFT, beamforming, etc. have been implemented using this system. The efficiency and speedup are given in this paper. This parallel signal processing system is suitable for many kinds of sonar systems.
