High-level computer languages are created to be understood by humans. As a result, the keywords and the commands of these languages are easy to understand. Machine languages are harder to understand and operate.

For this assignment, you should assume that the memory cells at addresses F0 to F9 are in the machine described here:

Op-Code	Operand	Description
1	RXY	LOAD the register R with the bit pattern found in the memory cell whose address is XY
2	RXY	LOAD the register R with the bit XY
3	RXY	STORE the bit pattern found in register R in the memory cell whose address is XY
4	0RS	MOVE the bit pattern found in register R to register S
5	RST	ADD the bit patterns in registers S and T as though they were twos complement representations and leave the result in register R
6	RST	ADD the bit patterns in registers S and T as though they represented values in floating-point notation and leave the result in register R
7	RST	OR the bit pattern in registers S and T and place the result in register R
8	RST	AND the bit patterns in register S and T and place the result in register R
9	RST	Exclusive OR the bit patterns in registers S and T and place the result in register R
A	R0X	ROTATE the bit pattern in register R one bit to the right X times. Each time place the bit that started at the low-order end at the high-order end.
B	RXY	JUMP to the instruction located in the memory cell at address XY if the bit pattern in register R is equal to the bit pattern in register number 0. Otherwise, continue with the normal sequence of execution.
C	000	HALT execution

and that it contains the hexadecimal bit patterns described in the following table:

F0	20
F1	C0
F2	30
F3	F8
F4	20
F5	00
F6	30
F7	F9
F8	FF
F9	FF

1. Explain (in detail) each step of the machine cycle. Show the contents of each of the registers and each of the memory cells after the execution of the code.

2. Compare and contrast machine and high-level languages using resources from the Internet or AIUs library. Be sure to explain why the hexadecimal and binary codes are important for programming in both languages.
