Chapter 2.3, Problem 1QE
Program Plan Intro
In a computer processor, program counter is used as a register with the location of the instructions. The program counter increases by its 1 value, whenever each instruction gets fetched.
Instruction Register:
The machine cycle is defined as first instruction is fetched into instruction register, it is decoded by the CPU and then it is executed. Instruction register holds the data or address which is being decoded and executed.

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?
Load AC from memory location 62h.
Add the contents of memory location 451h to AC.
Store AC to memory location 8h.
Store AC to I/O device number 8h.
if BX=1000, DS=0400, and
AL=EDH, for the following
instruction: MOV [BX] +
1234H, AL. the physical
address is
O 6243H
O 4234H
O 6234H
O 6324H
O 4244H
What is the effective address that is targeted by the store instruction whose code word in binary is:101011 01000 10001 1111 1111 1111 1100Assume [$t0]=0x400C
