Square root algorithm for 8051 microcontroller

目前已有若干版本的子程序库公开发表，它们各有特色。本程序库中的开平方算法为快速逼近算法，它能达到牛顿迭代法同样的精度，而速度加快二十倍左右，超过双字节定点除法的速度-At present, a number of published versions of the subroutine library, they have their own characteristics. The library of the square root algorithm for fast approximat

卡尔曼滤波是以最小均方误差为估计的最佳准则，来寻求一套递推估计的算法，它适合于实时处理和计算机运算。 -Kalman filter based on minimum mean square error for the estimation of the best criteria to seek a recursive estimation algorithm, which is suitable for real-time processing and computing.

本程序库中的开平方算法为快速逼近算法，它能达到牛顿迭代法同样的精度，而速度加快二十倍左右，超过双字节定点除法的速度。-The libraries in the open square algorithm for rapid approximation algorithm, it can achieve the Newton iteration method the same precision, and about twenty times faster, more than double by

这是一种改进的最小均方算法，算法具有较快的收敛速度和较低的稳态误差，计算简单。(This is an improved minimum mean square algorithm. The algorithm has fast convergence speed and low steady-state error, and the calculation is simple.)
