x$86$Assembly Language Programming

The Calculator$$s Specifications

This project asks you to design and implement a calculator using x$86$assembly language program.

To this end, you individually will build an application program as described in the steps next:

$1.$The program will take input from the user, and display the resulting output, both of which

will be carried out through the terminal window.

$2.$The input mathematical expression will be parsed $($PEMDAS rule will be utilized as a

standard for this$)$and analyzed for mathematical symbol identification for related

mathematical operation to be carried out. Please see the attached slides at the end of this

document for detailed description and a Java program as a sample implementation. The

detailed description slides use the Stack but you will be using your own defined memory

area which you are free to choose.

$3.$You will be implementing five mathematical operations using seven symbols in PEMDAS rule

for the mathematical expression to be evaluated as described next:

i$.$Open and closed parentheses symbols of $($and $)$respectively will be used for

separating sub$$expression$/$s $($ASCII codes are $28$h and $29$h respectively$).$

ii$.$The Caret symbol of $^$will be used for exponentiation $($ASCII code is $5$Eh$).$

iii. The Asterisk symbol of $*$will be used for multiplication $($ASCII code is $2$Ah$).$

iv$.$The Forward Slash symbol of $/$will be used for division $($ASCII code is $2$Fh$).$

v$.$The Plus symbol of $+$will be used for exponentiation $($ASCII code is $2$Bh$).$

vi$.$The Hyphen symbol of $$will be used for exponentiation $($ASCII code is $2$Dh$).$

$4.$An invalid expression should also be programmed and identified by the parsing phase, and

will be indicated as an output message of $$invalid expression entered$$on the Terminal

window. In case of valid expression, obviously the answer will be displayed.

It needs

One ASM file with clear sections of codes along with explicit commenting, headings,

implementation details for sections.

One MS Word$/$PDF file containing the screenshot$/$s of you
