Objectives:

Program writing for manipulating an array.

Tools$/$Systems:

$$ NASM assembler

$$ Tera Term

$8086$ Trainer $($including the cross$-$modem cable$)$

Lab:

$1.$ Consider the following arrays with the contents given $($you have to declare them in your program$).$

Array$1$:

$381312202519173013$

Array$2$:

Array$3$:

E$0$A$1+$E$9$A$2$ E$1$A$1+$E$8$A$2$ E$2$A$1+$E$7$A$2$ E$9$A$1+$E$0$A$2$

Write an assembly program to do the followings:

a$.$ Convert each of the even number in Array$1$ to its immediate next higher odd number and each of the odd number in the array to its immediate lower even number. This conversion will be done in a subroutine named Modifier. The modification will be done using logic so that the modifier works for any data in the given array. Before modifications, all the data in the array needs to be saved in the stack so that in future we can use the original data again.

b$.$ Now, populate Array $2$ with the saved data in the stack. Multiply each of the data $($only the even numbers$)$ by $4.$ This modification will be done by another subroutine named Incrementor.

c$.$ Now populate Array$3$ such that element $0$ of Array$3$ is the summation of element $00$f Array$1$ and element $9$ of Array$2.$ Element $10$f Array$3$ is the sum of element $1$ of Array$1$ and element $80$f Array$2$ and so on$.$

d$.$ Finally, send the content of element $0$ of Array$3$ to PORT $0$ of the trainer kit.

Process and procedures:

$1.$ Write the complete assembly program on notepad. Assemble it using NASM.

$2.$ Download the program into the $8086-$trainer kit through Tera Term.

$3.$ Demonstrate the program and the result by executing your program. Get your professor$$s initial.
