摘要
本文介绍了一种用于多道地震数据采集系统的实时相关器，它根据地震数据的的特点和对实时相关处理的要求，采用目前最先进的数字信号处理器TMS320C40，构成了一个多片C40并行数据处理系统，文章介绍了实时相关器的并行结构以及C40相关运算的软件流程，最后结出了测试结果。
This paper introduces a new kind of real-time correlators for multichannel seismic data ing systems According to the character of seismic data and the requirements for real time correlation, a multichip TMS320C40 Digital Signal Processor parallel data processing system is built The paper describes the system configuration of real-time correlators and the flowgraph of correlating softwere with C40. Finally it givesmeasurament results.
