摘要
为满足大地电磁测深（MT）信号现场处理的要求，本文在分析与优化MT信号处理算法的基础上，提出以TMS320C30高速浮点数字信号处理器构成主从式信号处理系统，其运算速度比用Fortran及其他语言编写的程序在IBMPC机上运行要快几十倍，运算精度比用定点数字信号处理器TMS32020高．文中讨论了软件设计方法并给出测试结果．本文为解决MT信号野外采集的现场处理的计算瓶颈提供了一种有效的途径．
To meet the speed requirements of Magnetotelluric (MT) sounding signal processing in situ,the master-slave signal processing system with a high speed Digital Signal Processor (DSP)-TMS320C3p is presented, which is based on the algorithmic analysis and optimization of MT signal processing. The operation speed is much higher than that programmed in Fortran and other languages on a microcomputer of the same speed such as IBM PC/AT, and the calculation precision is much higher than that with fix polnt DSP-TMS32020. The software design methods are discussed and the speed test results are given. A valid way is provided to solve the bottle-neck of MT singal processing in situ.
