Question

0001 = Load AC from memory

0010 = Store AC to memory

0101 = Add to AC from memory

0011 = Load AC (the accumulator register) from an I/O device

0111 = Store AC to an I/O device

With these instructions, a particular I/O device is identified by replacing the 12-bit address portion with a 12-bit device number. Remember that a number ending with a small ‘h’ means the number is a hexadecimal number.

What is the hexadecimal string that expresses the following instructions?

  1. Load AC from memory location 62h. 
  2. Add the contents of memory location 451h to AC. 
  3. Store AC to memory location 8h. 
  4. Store AC to I/O device number 8h.
