Ise $8086$ Instruction set for assembly language and write using the code segment in the picture.

Convert binary to unsigned int

Problem: Convert a binary string to decimal. Accept buffered user input in the form of a $16-$bit binary string. Convert to unsigned integer and print to the screen. If the user enters less than $16$ bits, you may pad the binary number with zeros on the left.

Hint: To print the numbers, you have to modify the print int tat example file $($the file is on Nexus$).$ That version uses division for $8$ bits, but you need division using $16$ bits for this assignment.

Sample Execution:

Enter a $16-$bit binary number: $1001111001011100$

The decimal unsigned integer equivalent is $40540.$

Enter a $16-$bit binary number: $01100$

The decimal unsigned integer equivalent is $12.$

Convert binary to signed int

Problem: Convert a binary string to decimal. Accept buffered user imput in the form of a $16-$bit binary string. Convert to signed integer and print to the screen. If the user enters less than $16$ bits, or inputs illegal character, return an error message and prompt for input again.

Sample Execution:

Enter a iboblt binary number: $1002111001011100$

The decimal signed integer equivalent is $-24996.$

Enter a $16-$bit binaty number: $11091021100$

Error: Please enter exactly $16-$hits: $1001111001011100$

Error: Illegal characters detactod. Please enter a $16-$bit binary number: $1001111001011100$

Evaluation

$10$ marks will be awarded for correctly converting to unsigned int and stgned int $($i$.$e$.10$ marks each$).10$ marks are for implementing error mensuge in Problem $2.$ The remaining to matk are style points based on subjective evaluation of the quality of your solutions and zaif comments $($amother tor maks each$)$
