Description

technical field [0001] The invention belongs to the technical field of signal processing, and in particular relates to a DPU-based underwater acoustic signal processing system and method. Background technique [0002] At present, most underwater acoustic signal processing servers use servers based on CPU chips and DSP chips to process underwater acoustic signals. Among them, the main control CPU module not only serves as the calculation function, but also preprocesses the underwater acoustic data at all times. At the same time, the CPU module is also responsible for the network reception of the underwater acoustic data, storage service management and other tasks, resulting in high resource requirements for the CPU, and the CPU is always under high load. It runs under high power consumption and consumes a lot of power. When storing and unloading a large amount of data continuously, the CPU resource requirements are extremely high, and it is easy to cause CPU downtime and redu...
