中文摘要:
      高性能和小型化是水声设备的重要发展趋势,研究嵌入式Linux平台在水声设备中的应用十分有意义。TI公司开发的OMAPL137芯片采用独特的DSP与ARM相结合的双核结构,具有集成度高、硬件稳定性强、速度快、开放性好等特点。研制了基于OMAPL137平台的数字信号处理分机系统,并对复相关测频算法在该平台上的实现方法进行了研究。具体包括该算法的原理分析,嵌入式Linux交叉编译平台的搭建、内核的编译下载、基于ARM与DSP双核操作系统的通信方式以及算法的硬件实现方法等,最后进行了电联调实验,实验结果达到了预期的效果。对于嵌入式Linux平台在水声设备中应用有一定的参考价值。
英文摘要:
      High performance and miniaturization is the important development trend of underwater acoustic equipment.Study of embedded Linux platform application in the underwater equipment is very meaningful.TI developed OMAPL137 chip uses a unique dual-core chip architecture,which combines a DSP core and an ARM core.This chip has high integration,hardware strong stability,fast speed,good openness characteristics.A digital signal processing system based on OMAPL137 platform is developed,and several main problems about the complex correlation algorithm realization based on the OMAPL137 platform are studied in this paper,such as the principle analysis of the algorithm,construction of embedded Linux cross compiler platform,compiling and download of the kernel,communication mode of dual operation system and the hardware realization of algo-rithm.The experimental research has been done and shows that the expected effect is achieved.This paper provides a reference for the embedded Linux platform application in underwater acoustic equipment.
