| 摘 要： | 针对地震数据处理中存在的数据交换效率低的问题,在分析传统地震数据文件存取基础上,提出一种基于内存映射的方法对地震数据处理.通过实验结果分析,基于内存映射的地震道集数据的存取效率高于传统方法近3倍,其中以全局方式映射地震道集数据耗时最短、效率最高.基于内存映射的地震道集数据存取有效的解决了这一问题,提高了在地震资料处理过程中的效率.

| Abstract: | The problem of low efficiency of data exchange in the seismic data processing,analysis on the basis of conventional seismic data file access,based on memory-mapped on the seismic data processing,a method proposed which used memory memory-mapped on seismic data processing in this paper.Through the analysis of experimental results,the efficiency of the seismic gather data based on memory-mapped access nearly three times higher than the traditional method,among these globally map the seismic gather data consumes the shortest time and the most efficient.The method that based on the memory mapping of seismic data access solved the problem effectively and improved the efficiency in the processing of seismic data. |
