Question

Write a hexadecimal machine language program that will add and subtract the following numbers:

45(10) + 45(16) - 13(10) - 13(16) + b(16) + (-5)(10).

That is 45 in base 10 plus 45 in base 16 minus 13 in base 10 minus 13 in base 16 plus b in base 16 plus negative 5 in base 10.

Save each of the instructions in memory and after the instructions save each of the values in memory, including the results. Display the results in hexadecimal and decimal. Run your program and display the memory cells to make sure everything works.

Explanation / Answer

here is the code for hexadecimal machine language program that will add and subtract the following numbers:

45(10) + 45(16) - 13(10) - 13(16) + b(16) + (-5)(10).

Simulator Version 4.0

Machinecode file = lab.mac Size = 17 (hex) = 23 (dec)
Microcode file = none Size = 93 (hex) = 147 (dec)
Config file = none
Log file = lab.log
Answer file = none
Simulation mode = horizontal
Microlevel = disabled
Shifter = one-position
Cmd line addr = F3C (hex) = 3900 (dec)
Load point = 0 (hex) = 0 (dec)
