MASM Assembly Program ONLY using Irvine32.inc

The program will use floating point instructions to compute the root solutions to the quadratic formula.

The program must repeat the calculation 1 million times calculating the time required to solve the formula.

The program should measure performance (Duration) of the program using the FPU instructions.

MAIN

1) Prompt for the coefficients ax^2 +bx +c.

2) Establish loop (ecx register =1000000)

3) Calculate start time (t1)

a) INVOKE GetTickCount

b) mov t1, eax

4) Using FPU instructions calculate

a) b + Sqrt(b^2 -4*a*c)/2*a

b) b - Sqrt(b^2 -4*a*c)/2*a

5) Repeat step4 until ecx==0

6) Calculate start time (t2)

a) INVOKE GetTickCount

b) mov t2, eax

7) Display the roots

8) Display the running time
