for（i=0；i!=8;i++）

{

ctrlcla.Channel[i].Current_all = Result[i]*cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].K0 + cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].B0;

}

把i等于01234567带入，如第一列

ctrlcla.Channel[0].Current_all = Result[i]*cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].K0 + cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].B0;
ctrlcla.Channel[1].Current_all = Result[i]*cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].K0 + cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].B0;
ctrlcla.Channel[2].Current_all = Result[i]*cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].K0 + cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].B0;
ctrlcla.Channel[3].Current_all = Result[i]*cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].K0 + cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].B0;
ctrlcla.Channel[4].Current_all = Result[i]*cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].K0 + cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].B0;
ctrlcla.Channel[5].Current_all = Result[i]*cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].K0 + cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].B0;
ctrlcla.Channel[6].Current_all = Result[i]*cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].K0 + cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].B0;
ctrlcla.Channel[7].Current_all = Result[i]*cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].K0 + cla_calib.Calib_Cur[i].Calibration[cla_calib.Point[i]].B0;

三种实现同样功能的代码，在CLA运行时时间分别为 500ns 1us 和3us

想问CLA是否也能够像设置CPU的opt一样进行代码优化的方式，还是编程时注意什么，由于控制需要频率很高，简单的几行代码就相差几个US，太让人头疼了
