地震资料数字处理具有运算重复性强、计算工作量大、算法比较固定的特点。比如通常使用的褶积运算的离散求和公式 y(n△)=sum form m=-M to M [h(m△)x(n△-m△)] 式中y(n△)——滤波后的地震信息; △——取样间隔; n——被滤波的地震信息的取样顺序号; m——滤波因子一半的取样点数。对于这样一个时间序列的数值的计算,是一个重复迭代的数学运算,需要计算机执行大量的乘法和加法操作才能完成。用一般的通用计算机来处理这类数学运算时,是用一个 The digital processing of seismic data has the characteristics of strong computational repetition, large computational workload and relatively fixed algorithm. For example, the commonly used convolution operation discrete summation formula y (n △) = sum form m = -M to M [h (m △) x (n △ -m △)] where y (n △) - Filtered seismic information; Δ - sampling interval; n - sampling sequence number of the filtered seismic information; m - sampling points half of the filtering factor. The calculation of a numerical value for such a time series is a mathematical iterative operation that requires the computer to perform a large number of multiplication and addition operations. Use a general-purpose computer to deal with such math, it is used
