基于数据库的通用驱动程序自动编写算法研究

Research on general driver programming algorithms based on database

传统的通用驱动程序自动编写算法编写耗时长,且错误率高。为了解决上述问题,基于数据库研究了一种新的通用程序自动编写算法,在驱动程序内部设定传输线,通过反射信号和入射信号的比值确定信号反射系数,判断传输线内部信号的负载阻抗和特征阻抗完成匹配算法,设定调解网络对驱动程序信号反射系数进行调节,使反射系数为0,利用梯度下降法减少编程程序内部误差,借助滤波算法将信号内部含有高频波纹分量过滤出去。为了检测基于数据库的通用驱动程序自动编写算法的工作效果,与传统编写算法进行实验对比,结果表明,研究的编写算法能够在短时间内编写出一套通用驱动程序,且错误率很低,该编写算法更加值得推广使用。

The traditional general purpose driver automatic programming algorithm takes a long time to write and has a high error rate. In order to solve the above problems,a new general automatic programming algorithm based on database is studied. The transmission line is set in the driver,the reflection coefficient of the signal is determined by the ratio of the reflected signal to the incident signal, the load impedance and the characteristic impedance of the signal in the transmission line are judged to complete the matching algorithm,and the modulation network is set to adjust the reflection coefficient of the driver signal. The reflection coefficient is 0,and the gradient descent method is used to reduce the internal error of the programming program. The high frequency ripple component in the signal is filtered out by means of the filtering algorithm. In order to test the effect of automatic programming algorithm for general purpose driver based on database,the experimental results show that the proposed algorithm can write a set of general purpose driver in a short time,and the error rate is very low. The algorithm is more worthy of popularization.
