Write a function (subroutine) that inputs a data value in register r0 and returns value in r0. The function returns y 5 a 1 bx 1

umka2103 [35]

Solution :

int f(int x){

$\text{return a + b*x +c*x*x}$ ;

}*/

int f( $\text{int R0}$ ){

int stack[2] = { $\text{R1,R2}$ };

$\text{R1 = R0}$ ;

$\text{R1 = R1}\times \text{ R1}$ ;

$\text{R2 = C}$ ;

R1 = R1 * C; /*R1 = $cx^2$ */

$\text{R2 = B}$ ;

$\text{R0 = R0}$ * R2; /* R0 = bx */

$\text{R0 = R0 + R1}$ ; /*R0 = $bx + cx^2$ */

$\text{R2 = C}$ ;

$\text{R0 = R0 + R2}$ ; /*R0 = a+bx+cx^2 */

$\text{R1 = stack[0];}$

$\text{ R2 = stack[1];}$

$\text{ return R0;}$

}

/* $\text{ARM code to implement the following C operation}$
