摘要
本文利用TI公司的TMS320VC5409系统DSP设计了吊放声纳数据处理硬件系统。充分使用DSP上的McBSP,作为多处理单元之间的数据传输通道,构建了硬件系统结构。系统构成简洁、稳定,并具有很好的扩展性和通用性。同时,使用DMA技术,使数据传输完全在后台进行,极大地提高系统的吞吐量和计算能力。系统设计符合现代硬件系统发展方向,可以满足大多数据吊放声纳的处理过程。
The Texas Instruments' Incorporated's TMS320VC5409 DSP is used to design the hardware of a data processing system for dipping sonar. By using three McBSPs on a chip as data paths between multi-processors, we construct the a brief and stable structure of the hardware system with good expansibility and universality is constructed. Simultaneously, throughput and processing ability of this system are increased greatly by the use of DMA technique, which transmits or receives data without intervention caused by the CPU. Furthermore, the design idea is coincident with the modern hardware development, and the system can accommodate most of dipping sonar processing instances for dipping sonar.
