$($ASSEMBLY LANGUAGE$)$Building on the program from the last assignment, a null$-$terminated string of ASCII character codes,

representing decimal digits as might be entered from a keyboard, are stored in consecutive bytes of memory

beginning at address STRG in RAM. Write a program to convert the decimal number represented by this

string of characters to the equivalent $32-$bit binary number, storing the result at address BINARY in RAM.

$($This is essentially a decimal to binary conversion.$)$ This program should be able to process strings of any

number of digits from one to the number corresponding to the maximum $32-$bit unsigned binary number.

For example, if you were to type the decimal number $"13587609"$ on the keyboard, the corresponding

characters would be stored in memory at STRG as follows:

$STRG=>\text{'}1\text{'}(0x31)-$ Most significant digit $(10,000,000\text{'}s)$

$STRG+1=>\text{'}3\text{'}(0x33)-$ Next most significant digit $(1,000,000\text{'}s)$

$STRG+2=>\text{'}5\text{'}(0x35)-$ Next most significant digit $(100,000\text{'}s)$

$STRG+3=>\text{'}8\text{'}(0x38)-$ Next most significant digit $(10,000\text{'}s)$

$STRG+4=>\text{'}7\text{'}(0x37)-$ Next most significant digit $(1,000\text{'}s)$

$STRG+5=>\text{'}6\text{'}(0x36)-$ Next most significant digit $(100\text{'}s)$

$STRG+6=>\text{'}0\text{'}(030)-$ Next most significant digit $(10\text{'}s)$

$STRG+7=>\text{'}9\text{'}(0x39)-$ Least significant digit $(1\text{'}s)$

$STRG+8=>000,-$ Null character

The corresponding BINARY value would be $00000000110011110101010010011001=0x00CF5499.$

Recall that the $k^{th}$ decimal digit of a number is weighted by a factor of ${10}^k.$

$D=1*{10}^7+3*{10}^6+5*{10}^5+8*{10}^4+7*{10}^3+6^{*}{10}^2+0*{10}^1+9$

This can also be computed by factoring out $10$ s as:

$D=((((((1)*10+3)*10+5)*10+8)*10+7)*10+6)*10+0$

The latter form might be easier to process for variable$-$length numbers since for each digit you multiply the

previous total by $10$ and add the new digit.

Execute the program two times $-$ once for each of the following character strings stored at STRG$.$

STRG: $.$asciz $"13587609"//$first test string

STRG: $.$asciz $"457"//$second test string

For the second test run, you can reset the processor and then enter the following command in the Debugger

Console to change the string and rerun the program without exiting the debugger.

set char $[4]*$ STRG $=457$
