基于交换架构的手持三维成像声纳设计

Handheld 3D Imaging Sonar Design Based on Switching Architecture

提出一种基于串行总线数据交互的芯片间及板间的总线交互结构数据通信解决方案,解决板上及板间数据传输的瓶颈问题,同时针对手持设备体积有限,散热困难等因素,设计一种利用高性能多核处理器和低功耗FPGA的平台结构,提出一种基于这种新型处理架构平台的水下远场频域三维成像算法。测试结果表明:该架构下的实时处理算法满足实时性要求。

Factors based on the serial bus data interaction between chips and between the boards the bus the interaction structure data communication scheme is proposed to solve the bottleneck problem of data transfer between the board and the board,for both the limited volume of handheld devices,cooling difficulties,design athe use of high-performance multi-core processor ＋ low-power FPGA platform structure proposed underwater three-dimensional imaging of the far-field frequency domain algorithm based on the new processing architecture platform. Simulationtests show that the algorithm meet the real-time requirment.
