Question

Help With this please

write an LC-3 program that produces the base 16 representation of a number of integers that are entered at the keyboard. You will use the extended trap for reading integers: TRAP xFB which reads an integer entered at the keyboard and places the integer value into R0.

Your program should continuously prompt the user for an integer from the keyboard. If the integer entered is 0 the program is to terminate. Each integer should be displayed, followed by the hexadecimal representation, such as shown below.

Sample program execution:

Be careful to test your program vigorously to ensure that it handles ALL valid 16 bit integers.

Explanation / Answer

.ORIG x3000
AGAIN       LEA   R0, PROMPT   ;Display the input prompt
       TRAP   xFB
       ADD   R0, R0, #0   ;Exit if the input integer is0
       BRZ   EXIT
       AND   R1, R1, #0   ;R1 = 16 (output base 16 HEXADECIMAL)
       ADD   R1, R1, #15
       ADD   R1, R1, #1
       TRAP x22       ;Print the integer in hexadecimal
       BRnzp AGAIN
EXIT               ;Loop exit point
   TRAP   x25       ;HALT program execution

PROMPT   .STRINGZ "Enter an unsigned integer (0 to quit)>"
.END
