Question

NEED HELP WITH THIS .

Write a MARIE assembly language program that would simulate calling and executing the following C function, as shown below: z = someFunction(a, b); where z, a and b are main( ) program variables, and the values stored in a and b are input by the user. The value stored in z will be output. Did your program execute correctly? This is the code for the function: int someFunction(int x, int y) { return 3 * x – 2 * y; }

Answer 1

Zero, DEC 0
X, DEC 2
Y, DEC 5
One, DEC1

1. LoadX // load X first
2. SubtOne // subtract one from X
3. Skipcond800 / skip if X-1 > 0 // if X-1 > 0
then skipcondition as 800
4.JumpL1 // otherwise jump L1
5.LoadX // loadX
6.AddX // add X value To X again
7.StoreY // store the value in Y
8.LoadZero // load the value 0
9.StoreX //store the value in X
10.L1: LoadY // load the value in Y
11.AddOne // add one to Y
12.StoreY //store the value Y-> Y+1
13.Halt // end
