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．
Based on the analysis and optimization of MT signal processing algorithm, this paper proposes a TMS320C30 high-speed floating-point digital signal processor to form a master-slave signal processing system to meet the requirements of field electromagnetic field (MT) signal processing. The computation speed ratio Programs written in Fortran and other languages run a few dozen times faster on an IBMPC machine than on the fixed-point digital signal processor TMS32020. The paper discusses the software design method and gives the test results. This article provides an effective way to solve the computational bottleneck of on-site processing of MT signal field acquisition.
