Assembly Language Visual Studio 2010 Exercise Part 2

Figure 1 is illustrates a hexagon figure with same length of side. To calculate the perimeter of the hexagon, the following formula is given.

Perimeter_hexagon1 = side1 + side2 + side3 + side4 + side5 + side6 Perimeter_hexagon2 = side1 + side2 + side3 + side4 + side5 + side6 TotalPerimeter = Perimeter_hexagon1 + Perimeter_hexagon2

Write a complete program using assembly language to calculate the perimeter of TWO different hexagons with different sizes.

In the program, you should do these steps:
 i. Get two values from keyboard (32-bit unsigned integer) and save into the variable name sideHex1 for the first hexagon and sideHex2 for the second hexagon.
ii. Calculate both of the perimeters (Example: Perimeter_hexagon1=18 à 3+3+3+3+3+3) by using LOOP instruction
. Save the first result in Perimeter_hexagon1 and the second result in Perimeter_hexagon2 (as 32-bit unsigned integer).
iii. Then, add the two perimeters and save in TotalPerimeter variable.
 iv. Display the output as shown in Figure 2.

Exercise 2

• Write a program in assembly language to multiple two unsigned numbers using multiple addition.

 • Your program should ask the user to input the multiplicand (n) and the multiplier (m). 

• The program will do multiplication of (n x m) by adding (n+n+n+n+ …) m times,

 • As example: o 2 x 5 can be calculated as 2+2+2+2+2 (in another word, adding 2 five times)

 • Your program should store the multiplicand, multiplier and the result in these variables multiplicand, multiplier and product respectively.

 • You must use LOOP instruction to do the addition. 

 • Sample output
