［求助］用汇编实现辛普森积分

怎样用汇编语言实现辛普森数字积分？

下面是C程序，哪位能帮忙搞个汇编版本的？只要有辛普森函数那部分就可以
/*-------复化辛普森求积公式---------*/

#include
#include
#include
#define N 100
/*-------将要被求积的函数------*/
double f(double x)
{
return 1.0/x;  /* 根据你需要，自定义函数*/
}
/*---------辛普森函数---------*/
double simpson(double low,double high)
{
double h; /*定义小区间*/
double odds=0.0,evens=0.0; /*分为奇区间和偶区间*/
double x;
double area=0.0; /*最终结果保存在area中*/
int k;
h=(high-low)/N;
for(k=1;k x=low+k*h;
odds+=f(x);
}
for(k=2;k x=low+k*h;
evens+=f(x);
}
area=(high-low)/(N*3)*(f(low)+f(high)+4*odds+2*evens);
return area;
}

main()
{double lower,upper; /*定义积分上下限*/
double swap;       /*用于交换上下限，当上限小于下限时*/
double area=0;
int ture=1;
do{printf("\n-----Interation by Simpson's method.-----\n ");
printf("Enter the lower and upper for interation:\n ");
scanf("%lf%lf",&lower,&upper);
if(upper < lower)
      {swap=lower;lower=upper;upper=swap;}
printf("\nIntergrating f(x) for %lg to %lg\n",lower,upper);
area=simpson(lower,upper);
printf("Area=%lg\n",area);
printf("pass 1 to continue 0 to exit:");
scanf("%d",&ture);
}while(ture);

}
